JEE Main Physics question
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. [AIEEE 2007]
Answer: (C)
Solution
Once a common (quasi-static) acceleration is established, both blocks move together with a =
