Question

A spring compressed by 0.1m develops a restoring force of 10N. A body of mass 4 kg is placed on it. Deduce the 

1. force constant of the spring 

2. depression of the spring under the weight of the body 

3. period of oscillation, if the body is disturbed.

Answer 1

Given 

Restoring force, F = 10N 

Mass of the body, m = 4kg 

displacement, x = 0.1m

 

= 100 Nm^-1

2. Depression due to weight

3. Period of oscillation T 

 

= 0.4 πs

T = 0.4 πs.
