Hello!!!
Hope you are doing great!!!
Given force of rope at free end = P
Given Mass of block = M
Given mass of rope = m
Let the force exerted by the rope on block = T
Let the common acceleration be = a
For block,(force),, T=Ma
for rope ,(force) ,,P - T=ma
=P-Ma = ma
=P=(M+m)a
=a=P/(M+m)
We have to find T,,,, So,,T=M*(a)
= T=MP/(M+m)
Hope it helps!!!!
