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 aconstant force F starts acting on the block of mass M to pull it. Find the force on the block of mass m

1.	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 aconstant force F starts acting on the block of mass M to pull it. Find the force on the block of mass m
Answer» `(MF)/M` `((M+m)F)/m` `(mF)/((m+M))` `(MF)/((m+M))` ANSWER :C
