18:32 First step - force = G× M×m/r² Second step - force =( 6.67×10·¹¹)×(6×10²⁴)×1/(6.4×10⁶)² Third step - force =6.67×6×1\6.4×6.4×10·¹¹×10²⁴/10⁶ Fourth step - force =40.02/40.96×10¹³/10¹² Fifth step - approx 9.77 Newton so, then approx 9.8 ms-² because according to book
18:20 answer F=Gmm/r^2 F=6.67×10^-11×6×10^24×1/(6.4×10^6)^2 F= 6.64×6×1×10^-11×10^24/ 6.4^2×10^12( 10^12 because 6×2) F= 40.02×10^13 / 40.96 × 10^12( 10^13 because of a rule in the exponent rule which is X^m × X^n = X^m+n ) F= 10×40.02 /÷ 40.96 (10^1 because of a rule in the exponent rule which X^m÷X^n = X^m-n ) F = 10× 0.977-( appox) ( 0.977 is because we divide or cut 40.02 by 40.96 so, we got 0.977) F= appox 9.77 This is my first comment pls like this comment if you like explaination and the answer is 100% correct

1. C) 1.66N 2. B) N m²/kg² 3. C) 8 times 4. A) The bouyant force will increase as the cork is immersed 5. i) N ii) Pressure in B>A iii) Pascal iv) True
alr look, Mass he can lift on earth = 15kg Force = 15*10 = 150N --------------- i We = mg = 15*10= 150N Wm = m*g/6 -------------------------------ii questions says that bros limit is 15kg, so he will apply the same force on moon and earth both F= mg (earth) F= m*g/6 (moon) 150 = m*g/6 ------------from eq i and ii 150 = m*10/6 150 *6/10 = m 90 = m So, bro can lift 90kg on moon

I lost all my hope before these half yearly because I didn't have any coachings but randomly I saw your video on my home page and now...I can't even think of failing. You motivated me, inspired me and taught me that I can do it..thank you so much for your amazing videos, you really are a pure soul bhaiya💗 Edit: My half yearly exam went really well even though I studied the gravitation chapter 3 days before my exam with this one shot, This was the best exam of science that I took ❤️
1:31:00 Bhaiya mujhe Top 5 questions me 3 number wala question samajh nahi aaya lakin main use question ko samajhne ki koshish ki aur mujhe samajh a gaya😅
GMm2/(r/2)² GMm2/(r²/4). (R square= r² and 2² = 4) Then according to fraction properties, 4 will go up and get multiplied so GMm2×4/r = GMm8/r². If you have any doubts then you can ask ChatGpt, i use it only.
@Yash_6765 No problem bhaiya, baat hai ki Mai class 5 Mai padhta hu aur Mai JEE prep kr rha hu to mai 9 science and maths krta hu. Aap ChatGpt use kr sakte hai doubts solve krne ke liye, bht mast hai
Bhaiya the acceleration due to gravity of an object when thrown upwards will be negative because it is the opposite to the force of gravity..😊 and positive when thrown downwards
sir pls start posting one shot revision videos (10-15min) of each ch class 9 and 10 that we students can sum up all the things studied. btw love your way of teaching.
Aaj sab Newton ko jante gravity ke liye par koi the great bhaskaracharya jhinho ne 500 years pehle hi is gravitation ka investion kia jise " गुरूत्वाकर्षण "ka naam diya.. par afsoos aaj kaun un great logo ko janat hai😢 jo janta hai like
IMPORTANT NOTE:- Brothers and sisters please do notice that the value of g, when throwing upwards is always negative but when dropping to the ground the value of g is positive. *This is given in NCERT book only Please check*
@@shyam_sharma121bro just asking as per me g which is gravitation so when it goes down it's negative as in the concept of free fall too and when it goes up it's positive
I really just appreciate how he is uploading the one shot video for chapters in such less time ✨️ we told for tissues, he did that..we told for force and laws of motion, he did that..we told for gravitation, he did that too! Like people are demanding for many chapters as their exams are near, and he's just fulfilling every single demand of ours..in such less time, it's not easy to teach these chapters, to prepare the presentation and THAT TOO with uploading more videos for motivation, study strategy n all that stuff..even NOW we are demanding for many chapters..at last, I just want to THANK YOU bhaiya for this much struggle that you do for us..our THANK YOU cannot be conveyed into words...THANKS A LOT
To find the maximum mass a person can lift on the Moon, we'll use the following steps: 1. Identify the force applied on Earth (F_Earth) to lift 15 kg. 2. Calculate the acceleration due to gravity on Earth (g_Earth) and the Moon (g_Moon). 3. Use the force and accelerations to find the mass that can be lifted on the Moon. Constants: - g_Earth = 9.8 m/s² (acceleration due to gravity on Earth) - g_Moon = 1.62 m/s² (acceleration due to gravity on the Moon) Step 1: F_Earth = m_Earth × g_Earth F_Earth = 15 kg × 9.8 m/s² F_Earth = 147 N Step 2: Since the same force (F_Earth = F_Moon) is applied on the Moon: F_Moon = m_Moon × g_Moon 147 N = m_Moon × 1.62 m/s² Step 3: Solve for m_Moon: m_Moon = F_Moon / g_Moon m_Moon = 147 N / 1.62 m/s² m_Moon ≈ 90.7 kg Therefore, on the Moon, a person can lift approximately 90.7 kg using the same force required to lift 15 kg on Earth.

Nah!!! g is a type of acceleration only... Acceleration is a vector quantity so the signs are used according to the Cartesian plane... Kyuki gravity hamesha niche hi lagti h to isliye - ayega 👀

18:20 answer
F=Gmm/r^2
F=6.67×10^-11×6×10^24×1/(6.4×10^6)^2
F= 6.64×6×1×10^-11×10^24/ 6.4^2×10^12( 10^12 because 6×2)
F= 40.02×10^13 / 40.96 × 10^12( 10^13 because of a rule in the exponent rule which is X^m × X^n = X^m+n )
F= 10×40.02 /÷ 40.96 (10^1 because of a rule in the exponent rule which X^m÷X^n = X^m-n )
F = 10× 0.977-( appox) ( 0.977 is because we divide or cut 40.02 by 40.96 so, we got 0.977)
F= appox 9.77

F = 6.67 ×10^-11 × 200 × 80 / (6)²

F = 667 × 10^-11 × 80 / 18 (therefore 667 ×80 = 53360)

44:16 mass will remain same that is 15 kg also on the moon
No bro it's answer is 90kg
Can anyone tell me the right answer with whole explanation because my answer is 2.5
alr look,
Mass he can lift on earth = 15kg
Force = 15*10 = 150N --------------- i
We = mg = 15*10= 150N
Wm = m*g/6 -------------------------------ii
questions says that bros limit is 15kg, so he will apply the same force on moon and earth both
F= mg (earth)
F= m*g/6 (moon)
150 = m*g/6 ------------from eq i and ii
150 = m*10/6
150 *6/10 = m
90 = m
So, bro can lift 90kg on moon

I lost all my hope before these half yearly because I didn't have any coachings but randomly I saw your video on my home page and now...I can't even think of failing. You motivated me, inspired me and taught me that I can do it..thank you so much for your amazing videos, you really are a pure soul bhaiya💗
Edit: My half yearly exam went really well even though I studied the gravitation chapter 3 days before my exam with this one shot, This was the best exam of science that I took ❤️

1:31:00 Bhaiya mujhe Top 5 questions me 3 number wala question samajh nahi aaya lakin main use question ko samajhne ki koshish ki aur mujhe samajh a gaya😅
Mujhe bhi 3 number wala question samjah nhi aaya
Could u please explain me??
GMm2/(r/2)²
GMm2/(r²/4). (R square= r² and 2² = 4)
Then according to fraction properties, 4 will go up and get multiplied so GMm2×4/r = GMm8/r².
If you have any doubts then you can ask ChatGpt, i use it only.
@Chronox-c4c Thanks Bhai question 3 samjhane ke liye
@Yash_6765 No problem bhaiya, baat hai ki Mai class 5 Mai padhta hu aur Mai JEE prep kr rha hu to mai 9 science and maths krta hu. Aap ChatGpt use kr sakte hai doubts solve krne ke liye, bht mast hai

Bhaiya the acceleration due to gravity of an object when thrown upwards will be negative because it is the opposite to the force of gravity..😊 and positive when thrown downwards

IMPORTANT NOTE:- Brothers and sisters please do notice that the value of g, when throwing upwards is always negative but when dropping to the ground the value of g is positive.
*This is given in NCERT book only Please check*
Yess
But bhaiya said that g is negative because it goes 👇 down ward
@@gamingwithadi3279 bruh, g should be positive while going downwards and negative when going upwards
@@shyam_sharma121bro just asking as per me g which is gravitation so when it goes down it's negative as in the concept of free fall too and when it goes up it's positive

I really just appreciate how he is uploading the one shot video for chapters in such less time ✨️ we told for tissues, he did that..we told for force and laws of motion, he did that..we told for gravitation, he did that too! Like people are demanding for many chapters as their exams are near, and he's just fulfilling every single demand of ours..in such less time, it's not easy to teach these chapters, to prepare the presentation and THAT TOO with uploading more videos for motivation, study strategy n all that stuff..even NOW we are demanding for many chapters..at last, I just want to THANK YOU bhaiya for this much struggle that you do for us..our THANK YOU cannot be conveyed into words...THANKS A LOT
Yeah even I was thinking about it whatever till now he has taught is too much for us and yes ofc big thanks to him ❤👍🏻
i agree 100% dude its the same story for me too, YOU SPEAK FOR US!
baat to sahi hai yaar . He is so hard working ❤❤🔥🔥
To find the maximum mass a person can lift on the Moon, we'll use the following steps:
1. Identify the force applied on Earth (F_Earth) to lift 15 kg.
2. Calculate the acceleration due to gravity on Earth (g_Earth) and the Moon (g_Moon).
3. Use the force and accelerations to find the mass that can be lifted on the Moon.
Constants:
- g_Earth = 9.8 m/s² (acceleration due to gravity on Earth)
- g_Moon = 1.62 m/s² (acceleration due to gravity on the Moon)
Step 1:
F_Earth = m_Earth × g_Earth
F_Earth = 15 kg × 9.8 m/s²
F_Earth = 147 N
Step 2:
Since the same force (F_Earth = F_Moon) is applied on the Moon:
F_Moon = m_Moon × g_Moon
147 N = m_Moon × 1.62 m/s²
Step 3:
Solve for m_Moon:
m_Moon = F_Moon / g_Moon
m_Moon = 147 N / 1.62 m/s²
m_Moon ≈ 90.7 kg
Therefore, on the Moon, a person can lift approximately 90.7 kg using the same force required to lift 15 kg on Earth.
Sach sach bolna chatpgt se uthaya hai n😂
chatgpt ahh comment
1:18:15 if both force are same the object will float and sink both atq ncert
Actually if the forces are same , the object will be Submerged into the liquid and remain their until the forces are same

True becoz direction cannot be 0
Nah!!!
g is a type of acceleration only... Acceleration is a vector quantity so the signs are used according to the Cartesian plane...
