Completing my class 11th Backlogs with full sincerity and solving 250 to 270 questions daily (including all 3 subjects). Thank you sir, I promise I will consistently do hardwork. 💪📖📝
including theory too? or theory is completed??
Us bro
@@ramanified Backlogs include half understood theory or never studied theory
itne jyada questions mat kar abhi .
if tere mains ke mock mein 150+ aa rahe then do tough questions , matrix , comprehension .
@padhlebhai982 So how was your JEE result ??
I will develop a program to identify the lone who disliked this video, ni mtlb kahan se aate honge aise log🤷🏼♂️
Whatever sir u are a legend of physics 🙏🙏
Amazing content sir 😊😉.Never seen any team or techer like compentishun. Uploading all possible contents of the chapter taking from level of board to Jee-Advanced. We are blessed such that we meet u on this platform sir keep doiing hard work we will also produce result.
Do u got selected??
Sir i am improving day by day...Thnx a lot sir 🙏🥰
Studying from now . Have one year for jee advance class 12 from scratch (march) will crack jee at any cost with rank under 2000.
Ho gyi kya bhai

Awesome Sir ..
I have completed my engineering..
Still , i am enjoying your lecture..
I have never seen such type of contents..
You are the best teacher..
You are great sirrr ur valuable suggestions are quite apppreciableee
I want to become a teacher just like you sirrr you would be always my inspiration and motivation .....thankd to u sirrr....
This is a great video sir. Made my concepts crystal clear
Awesome teaching methodology sir👍🙏🏼🙏🏼🙏🏼🙏🏼
Best channel with complete jee package..❤️🙏
advance level content 💛💛💛💛
very helpful and geniune content
thanks team
Great lecture ❤️ thanku sir 😊🙏🏻
Abj sir jindabaad , jindabaad ............
Thank you so much sir love from up
It is great video in youtube channel❤❤❤❤......
starting today, I promise I will be focused throughout !!
Have you completed it ...? Was it very helpful?
Great teacher ❤️❤️❤️❤️👌👌👌🤘🤘🤘
1:29:30 I have joined another coaching still this is applicable for me thanks for guiding me.
bhai tera iit hua?
@@kkkk-su7oh see his name
@@sahebOp_yeah congrats to him
@@sahebOp_aapke name pe bhi IIT lag gaya😢
Sir you take example of work done by Kinetic friction the friction is static friction is there therefore the acceleration is same on both block that is 2m/s²
amazing video sir
35:00 very good conceptual question 👍
Circular motion and centre of mass kab suru karoge sir
ABJ sir = 294k selections ....sir amazing content sir. And. Sir modern physics kb start hogi
Best teacher..❤️
Can't stop my eyes looking at you♥️♥️
Thank you sir!
fair enough.......
Sir please update and arrange the playlist and competishun app
'Next is' how sweet voice
Thank you sir....
sir can we do chain pulling question with the help of centre of mass like the work done to pull the centre of chain is the total work done to cover up whole chain instead of integration we can use it
Legend🔥
Sir in variable kinetic friction example, l stands for full length of path or displacement
thanku sir for teaching us
no one is as great as mohit sir
he is brilliant..
ABJ sir is best bro

sir sheets kaha se milegi? i am new to this channel so idk please reply

sir at 1.26minutes direction is changing how yu kept force as constant
Sir you are super
Thanks sir
thank you sir
sir at 57:42 why we wrote force as kx instead of k(x+dx) as we are considering that we displace the end by dx
dx is very very small in comparison of x so assumption
Sir 5 kg mas aur 10kg mass ko add karke maine normal nikala tho kya vo sahi nhi kya
Sir maths key liye rd sharma and pervious year jee questions are enough Or not. Please tell me (mt sir) 🙏🙏🙏🙏🙏🙏🙏🙏 sir pls ask him, please🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
@@cuetcompetishun ok sir thanku very much and for advance what should I follow because I don't have any coaching material sir.
sir jaante hain humko integration wagera mein samjh nahi aata ... isliye wo formula bhi dete hain and diagram ke through achhe se 2-3 baar batate hain ....
thank you
Sir I am following maths and physics lectures of your channel for jee preparation. Sir will I able to clear jee without any coaching.
yes brother. Just keep practising after learning. Doing problems in maths and physics is very important. All the best :)
@@jaygondaliya6245 💀💀
59:18 pls tell me when we find work done from initialially elasting to its natural position then it come +1/2kx^2 but when we prove this integration then upper limit is 0 and lower limit is x so ans is -1/2kx^2
no in both cases it is negative i.e -1/2kx^2..Initially for extension spring expand in +ve x-axis and spring force is in -ve x-axis so spring force= -kx and limit is 0 to +x direction but in compression case: compression x is in -ve x-axis and force is in positive direction so spring force =+kx and limit is 0 to -x...Hope u get it

(rewatch the skipped part)
Sir in which chapter cutting of spring and all is going to be taught!?
@@cuetcompetishun Okay Sir! I thought more of it is remaining.
Hello sir, I am interested in purchasing the paid course for math and phy
I want to know if there is doubt clearance facility available, and if so how?
Call@7410900901
Here, at 18:30, the block has Some velocity, So shouldn't there be a Force Too? Force Which is providing The Velocity?
acceleration must have been negligible so that force is not considered.
For displacement of B why he took - 1/2 at^2 32:18
Two block wale question mein force 60N h toh friction toh kinetic ho jaayga na sir ( as 60N is greater than fs max.) body mein relative motion hona chahiye na?
But condition is given they are moving together. If we consider 0.8 as static friction coefficient then kinetic friction coefficient will be 0.2 then kinetic friction will come out to be 20N.
#abjsir is best.
46:14 I am not able to understand how mass of chain was m/l (l-x) please help.
Ohh bro.. But don't worry
Suppose body of length l have mass m.... {L=M]
Therefore body of length 1 have mass m/l
So body of length l-x have mass m/l (l-x)
Thank you
@@world-rm9il Thank you Brother
Sir please teach the concept of variable mass . Thank you😀

Sir i live in guwahati. I am currently in 12th. My 11th is very weak and my 12th is also upto board level only. I have been only studying ncert. I have decided to take a drop after boards for preparation of iit jee. I am not financially weak. So, sir i want to know that from where should I study in my drop year. Should I take online coaching or offline or should I go with your RUclips videos and any dlp?
Please reply fast sir i am very much confused 🙏🙏

Sheet kaha pe available h sir...
Sir i want compitishun physics sheet

U r the best teacher of physics😍😍😍😍😍. Thanku so much sirr

Good morning sir
Sir just one question if one has to complete jee syllabus to advance level like devoting 10-14 hrs everyday as a dropper till when will one be able to completely learn the concepts and syllabus prior he/she is average from now????
Also sir I've been following your lectures all went good just sir my request is to put maximum chapters before jee m Jan 2021 pls guide sir

Thanks for selfless service sir
Pls sir also pls add physics section in competishun app

Sir, are gravitation lectures are completed??
🍓on the cake .
Sir does conductors are completed ???
Ok sir ,thank you sir
Is it sufficient for theory and sir what should we do after watching your lectures for practise which book ?? Thank you sir😌☺️

@Innovative Learningkaha sey yar
18:00
Sir how many lectures are left in WPE ???
@@cuetcompetishun okk sir
Sir I am in 11 th class currently.....
Sir I understand all the concepts but can't solve questions in physics....
Plz tell sir why....
Try solved examples first or you can checkout problem solving sessions on RUclips
Then go for unsolved questions
11th physics is comparatively harder, so don't lose faith. It is very common to feel you cant solve much. Study as much as you can right now. Once you reach 12th and study 12th physics a bit, come back to revise 11th physics and solve a couple of problems. By then, things should be easier for you.
It is also important to solve questions in a systematic way. Start with Solved examples(just go through them and understand). Then do JEE mains/NEET lvl before going to adv lvl. I would recommend you to start solving dpps and package of some reputed coaching institution
@@cutechicken2534 thank you brother
Sir is vibrant academy dlp enough for advanced

Thank you Sir

Sir where is sheet uploaded
Sir where is the sheet? Plzz reply please 🙏
42:00 - 48:00
@51:41 why is there an l in the denominator ? pls someone explain it
bro basic unitary method
suppose you have a 10m rope of mass 10kg
then each 1m of that rope will weigh 1kg
similarly each unit length of chain of length l and mass m will weigh m/l
for (l-x) length ,simply just multiply the weight of unit length i.e m/l(l-x)
hope this helps
