@Sneha_2021
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..
