A block of mass 'm' is connected to another block of mass 'M' by a spring (massless) of spring constant 'k' The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched Then a constant force 'F' starts acting on the block of mass 'M' to pull it. Find the force on the block of mass 'm' :

A

`(mF)/M`

B

`(M+mF)/m`

C

`(mF)/(m+M)`

D

`(MF)/(m+M)`

Text Solution

Verified by Experts
