A spring compressed by `0.1`m develips a restoring force 10N. A body of mass 4kg is placed on it. Deduce `(i)` the force constant of the spring `(ii)` the depression of the spring under the weight of the body `(` take `g=10N//kg)` and `(iii)` the period of oscillation, if the body is left free.

A spring compressed by 0.2 m develops a restoring force of 25 N. A body of mass 5 kg is placed over it. Deduce (i) force constant of the spring (ii) the depression of the spring under the weight of the body and (iii) the period of oscillation, if the body is disturbed. Take g=10 N kg^(-1) .

A spring compressed by 10 cm develops a restoring force of 10 N.A body of mass 9 kg is placed on it . What is the force constant of the spring ? What is the depression in the spring under the weight of the body? What is the period of oscillation if the body is disturbed from its equilibrium position?

On compressing a spring by 0.5 m, a restoring force of 20 N is developed. When a body of mass 5 kg is placed on the spring, then calculate the (a) force constant of the spring. (b) the distance through which the spring is depressed under the weight of the body. (c ) the period of oscillation of the spring if the the body is pushed down and then released.

When a spring is compressed by 0.05 m a restoring force of 10 N is developed in it. Then the force constant of the spring is

A spring is compressed by 10 cm by a ball of mass 20 g . What will be the potential energy of a spring if the force constant of the spring is 20 N cm^(-1) .
