A block of mass `m` having charge `q` is attached to a spring of spring constant `k`. This arrangement is placed in uniform electric field `E` on smooth horizontal surface as shown in the figure. Initially spring in unstretched. Find the extension of spring in equilibrium position and maximum extension of spring.

Initially block shown is at rest and the spring is unstretched, when a constant force F begins to act on it neglect friction. Find maximum extension in the spring

A block of mass m is attached with a spring in vertical plane as shown in the figure. If initially spring is in its natural length and the block is released from rest, then maximum extension in the spring will be
