Question

A block of mass `M` is pulled along a horizontal frictionless surface by a rope of mass `m` . Force P is applied at one end of rope. The force which the rope exerts on the block is:
A. F/(M+m)
B. F should be equal to the weight of A and B
C. FM/(m+M)
D. Zero

Answer 1

Correct Answer - C
`a=(F)/(M+m)`
Force on `M=Mxx(F)/(M+m)`
