Solution

Elastic force
It is a type of restoring force by which an object retains its shape after the removal of a force.
For example, when rubber is stretched by applying a force then a restoring force starts to act on it,
When the applied force is removed the rubber regains its shape due to the restoring force acting.
This restoring force is called elastic force.
Thus, the force involved in the mentioned case is elastic force.
