About This video :-
In this video, Deepak Gupta sir is explaining the concept of constrained motion or say constraint motion and the string constraint problems and numericals. Constrained motion is one of the very important topic of NLM that is Newton's Laws of motion. In this video, all the numerical problems asked in previous year's JEE and NEET Exams are discussed very well.
A block is dragged on a smooth plane with the help of a rope which moves with a velocity V as shown in the figure. The horizontal velocity of the block is:
In the figure shown, blocks A and B move with velocities v1 and v2 along horizontal direction. Find the ratio of v2/v1
A rod AB is shown in figure. End A of the rod is fixed on the ground. Block is moving with velocity 3 m/s towards right. The velocity of end B of rod when rod makes an angle of 60∘ with the ground is :
Two beads A and B move along a semicircular wire frame as shown in the figure. The beads are connected by an inelastic string which always remains tight. At an instant the speed of A is u, ∠BAC=45∘ and BOC=75∘, where O is the center of the semicircular arc. The speed of bead B at that instant is:

About This Channel:-
Dear students,
As you all know that IIT JEE Mains / Advance & NEET are one of the most prestigious and competitive exams of the country, for which lakhs of the students appear every year. These exams are known to be one of the toughest exams for which the students work very hard. A lot of coaching institutes provide good quality coaching and materials to the students so that their efforts and hard work can be reduced a bit. But as we all know that these coachings charge very big fees and a lot of students are not able to pay these big amounts.
That's why this channel Fun with Physics is created where you will find all the quality material for IIT JEE Mains / Advance & NEET explained by our expert faculty in a very simple manner, which is being taught at any coaching in India. You can ask your doubts in the comment box, which will be solved by our expert team very soon.
JAI HIND!

Sir aap or bhi chapters ke upar video bnao

[@parimal8929]

Sir please 🥺 mere kohivi teacher Nehi hai। 39.50 sec video me ek problem thi ek rod ka velocity batao । To tum bole। B point ka horizontal velocity route 3। M/s । Mere ek doubt tha ki rod ka harek particle ka velociti route 3 m/ s hongi

Please reply

beta, rod ke tip ki velocity route 3 m/sec di hui hai question me, Har ek particle ki nhi.

Due to the excessive Force it will break.

Awesome lecture

[@khabrikapala]

in the first numerical sir, why cant we take 5 cos53 = Vb? that was it also correct but answer will be different. Please help sir.

[@FunwithPhysics]

We have to focus on that velocity which is to be determined, and the concept is that, it doesn't matter, whatsoever be that velocity, just the component of that velocity along the string must be the same. I hope it hepls....😊😃 Feel Free to ask again.....😊💖

[@khabrikapala]

@@FunwithPhysics thank you sir but it will not be correct from maths point of view. I got the concept that you are saying but what is the logic behind not accepting the known velocity 's component along unknown. Why is that wrong

[@manjubhimra2344]

@@FunwithPhysics sir, I have been thinking about the same question for some time , I read your reply and I found it useful, In your reply as you have mentioned:- It is the concept that the component of the velocity of the object (which we have to find) along the string should be same as that of given velocity (in that case it was 5m/s) but my question is what's the problem in using component of velocity of the string along the horizontal (the concept John peters has mentioned i.e 5cos thetha) that also make sense...but as you mentioned the real and true concept but that doesn't gives the reason why taking 5cos theta is wrong? What I think(my explanation,why 5cos theta is wrong(I don't know whether it is correct or not ;))--- What I know so far is that taking the component of a Vector means knowing it's effect(more clearly what it can do) in X axis and y axis, So by taking component of velocity of string i.e 5costheta would mean what is the velocity of string in horizontal direction(5cos theta) and this velocity has nothing to do with velocity of box that's why I think 5cos theta can not be the velocity of box And component of velocity of box along the string makes sense becoz that would mean what is the velocity of box along the string which can not be different from 5m/s This is what I have figured out by thinking for a long time,,,,,,,but I am not sure whether I am correct or did I go wrong somewhere ? Eagerly waiting for your reply sir

[@amritendukanjilal1419]

We have to take the component of the velocity of the block along the line of the string and not the other way round
