Question

A block of mass m if 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.​

Answer 1

Explanation :-. Acceleration of system

• a = F/M+m

so force acting on mass

• F = ma = mF/ m+ M Answer
