Doubt from Laws of Motion


Ans: AB

someone plz try this!

irodov or krotov type proble i think reso paper?

Getting only A . Does anyone get B

Can you try this?

sir assume 2 min situation as both lose contact take one moving with acceleration upward and vice versa with a_1
then T=F/2
and put in equation use a=dv/dt now you may have to integrate it from 0 to 2 and i think time should also be given but please see this step may be without that u can do it i m solving in mind so mistake can commited by me..




I considered a case where the 10 kg block remains at rest as the pulley is pulled.
