here idts u need to loook from b's frame for circular motion as we use tht mroe when we need to find tension and stuff, here directly momentum conservation and energy and vel along string should work
I got the solution
But how to know when to go in someones frame or not
Did a quesn like this one time, usme frame mein leke kara tha
good que
ans mile toh batana
yea it was the pathfinder one iirc, in that remember how we used tension to determine when the ball will lift off the floor right? in tht we dealt w forces and all thts why tension, u should use circular motion concept when findign tension and forces etc, for normal ques like this conservation laws r adequate
ques bhejna
are nahi nahi bhai pathfinder nahi koi aur. vese bhejdo aap jiski baat krre ho
Ye to mene hi bheja tha
yea we observed from b's frame in this for tension
pls wait close mat karna . time milega toh dekhta u
Can we do this one with frame. Even though aapka tareeka easy ha but tbbhi
idts since what will we even do after entering in frame ? how will we find out velocity at end etc etc, so idts thats the wy to go here
