HW : w= mg= N 2×10 = 20 N=> Nf Coefficient of static friction(mu) =0.4 fs = (mu)s× N = 0.4 × 20 = 8 N But, even the 4N is acting on the object but the fsmax will cancel the force because it is Self Adjusting Force and the force is the less than fsmax ... 😊
Wrong, this is limiting force or f max so to move the block you need more than 8N force the force applied on the block is 4N since friction force is self adjusting it will adjust itself to 4N and cancel the force applied So the answer is 4N
This is an outstanding video! Your efforts in providing accurate and reliable information are highly commendable. The video is perfectly organized, and your detailed explanations are exceptionally comprehensive. Wishing you all the best in reaching 10 million followers!
Bro static friction (fs) is variable means it depends upon the applied force(F) but we know their will be a fs max of a body Let fs max = 10N and F = 8 N Since fs ( not fs max) is a variable force and is equal to applied force (F) Therefore, fs=8N i.e., 0
In rolling friction 0.02*10N/1m means in the we get it's unit as N/M but frictional force unit is N how is it possible I want to understand and send me the details of the same to attend the class THANK YOU.
Solution is here Given Ms=0.4 Mass=2kg Applied force=4N Find force of friction Soln. N=W W=Mg =2x10=20 Msmax=MsxN =0.4x20 =8N Hence we need to produce more than 8N.but the Applied force is only 4N ,thus the object can not be moved.And answer for question =8N
The applied force is 4 newtons. 8N is the maximum static friction. That question is not asking you for maximum static friction. Calculate the force of friction between the floor and the block. We all know the FS max = 8N. But 4N has already been applied to the block. You need to subtract the "4N" applied force from maximum static friction 8N - 4N = 4N 4N is the force of friction between the floor and the block since 4N force has been applied to the block

HW : w= mg= N
2×10 = 20 N=> Nf
Coefficient of static friction(mu) =0.4
fs = (mu)s× N
= 0.4 × 20
= 8 N
But, even the 4N is acting on the object but the fsmax will cancel the force because it is Self Adjusting Force and the force is the less than fsmax ... 😊
You are correct
👍👍👍
I think the answer would be 8N because--
M= 2 KG
W= mg
= 2 KG*10 m/s²
= 20N
Coefficient of static friction= 0.4
therefore, 0.4*20N= 8N
Wrong, this is limiting force or f max so to move the block you need more than 8N force the force applied on the block is 4N since friction force is self adjusting it will adjust itself to 4N and cancel the force applied
So the answer is 4N
your the best teacher i have ever listened to
thanks for your helpful teaching
Sir you explains very well with practicles
We are glad to have a 😊 such type of valuable classes by you sir
Why we should not used cos theta instead of tan theta to calculate angle of friction. Sir
Same doubt
Your explanation,teaching is awesome sir. Thanks a lot and lot .....for your service sir.
Welcome
Thanks
Really understood clearly the topic also enjoyed too....🤩🤩thanks sir for your support ❤❤❤

Hi I'm Solomon Manyuot Mabor, from south Sudan am so glad for the work you have done ✅✅✅👍👍🎉🎉🎉.
Thanks. Glad it helped you
Sir you explain really well thank you so much 😊🙏
You are a blessing to most students who watches you💯, I thank God that I am of your RUclips follower ❤❤❤❤
Thanks for liking
This helped me a lot when I was doing exams, Thanks! ❤❤
I am really glad I found ur channel please keep making such videos now got friction into my head and heart
answer to last question 8N.
This is most wonderful experience explanation, so I like it sir
Glad to hear that
Thanking you sir for your effective explanation.
You are most welcome
How you have taken mgsin and mgcos directly,why we get like that please explain in detail

Bro static friction (fs) is variable means it depends upon the applied force(F) but we know their will be a fs max of a body
Let fs max = 10N
and F = 8 N
Since fs ( not fs max) is a variable force and is equal to applied force (F)
Therefore, fs=8N
i.e., 0
The way u taught ch friction now i don't have any doubt in this ch u r superb sirr thankyuu so muchh ❤
You're most precious teacher in my Educational journey thank you for making physics look easy for me😊
This is really a very helpful video. Concept is Crystal Clear.
Glad it was helpful!
W=N
2×10=20N
So,fs=0.4×20
=8

Sir can you please upload vectors addition and subtraction.
We will definitely try to upload more videos soon!
Thank you sir
Thanks a lot sir...ur way of explaining is inexpressible 🙏🙏.
Please bring courses for 11 and 12 sir 😭🙏
Your welcome! Courses for Class 11 are coming in the first week of January!
@@ManochaAcademy for 12 sir?
@@ManochaAcademy pls launch courses for 12 also🙏🙏😭
You are an inspiration sir
Nice way of teaching

I like it sir and I understand well the concept of friction. Thanks for you sir😂❤
Bestt teacher 😊
Hello sir your explanation is very well
Love from Nepal❣️
Thank you so much 😀
The frictional force is 8N.
Therefore the applied force, 4N, is not sufficient to move the box.
Thank you sir for clear explanation about friction ❤
You are welcome
Great Video!!!
Thanks!
4 newton is the force of friction for the question sir
Thank s sir ❤😊
Hi,am benard from Uganda am happy to join you
Thanks Benard! Great to hear you like our videos! Do share it with your friends!
It's clay in generals. Language .
Can you suggest me a good science book for class 8 and 9
Good morning sir thank you ❤❤❤❤
Sir I am watching this video from Russia but I am also Indian .😊
Tomorrow is my exam
I need russion

In rolling friction 0.02 x10N/1m means in the final we get it's unit as N/m? But frictional force unit is N, how is it possible?
So wonderful topic
Hello sir thank you for explaining this topic i was trying to find this kind of vedio 😊
Your video is very helpful
World best video ❤️
Law of flight inertia and clay friction is inverse to one other.

Bolts are pin apliers for race.break.clutch (pateren at control 14 feet )(28feet)$cale and compos (180 scale:1.3.0 compos:90 balance)
Fs max is proportionate to weight not normal btw
Kinetic friction is also called as dynamic friction yes or no 🧐🧐🧐
Please can I get a video of calculation on this
Thanks sir tor explanation😊😊😊😊😊

THANK YOU.
finally i get to understand this topic well
How to calculate coefficient of friction?
thanks a lot for this amazing explanation! you deserve much respect!
Sir can you please make a video on tension
Why are you not replying people that solve the problem 😢 so that we can know the answer
Is the abs is 8N?
Solution is here
Given
Ms=0.4
Mass=2kg
Applied force=4N
Find force of friction
Soln.
N=W
W=Mg
=2x10=20
Msmax=MsxN
=0.4x20
=8N
Hence we need to produce more than 8N.but the Applied force is only 4N ,thus the object can not be moved.And answer for question =8N
❤
The applied force is 4 newtons. 8N is the maximum static friction. That question is not asking you for maximum static friction. Calculate the force of friction between the floor and the block.
We all know the FS max = 8N.
But 4N has already been applied to the block.
You need to subtract the "4N" applied force from maximum static friction
8N - 4N = 4N
4N is the force of friction between the floor and the block since 4N force has been applied to the block
Sir , what is fluid friction ?
Force and mas remain gravited this state any build ups .

Well teaching
Thank you sir
Very good sir
Sir class 9th also exampler book question answer and complite preparation (from bihar)
Is the answer 8N or 4N
Thanks sir
Amazing Video!
NO more friction to study this topic :)
Thanks
Frictional force i.e the limiting friction is 8N
answer is 4N
Is it 8N
Sir I know you have made videos on the electricity but they are not enough they not have many things
