Question

When an elastic body is in equilibrium in its altered shape, the magnitude of the external deforming force is ______.

विकल्प

• Equal to the internal restoring force

• Always less than the internal restoring force

• Zero, as the deformation is complete

• Always greater than the internal restoring force

Answer 1

When an elastic body is in equilibrium in its altered shape, the magnitude of the external deforming force is equal to the internal restoring force.

Explanation:

For the body to be in equilibrium (static state after deformation), the internal restoring force must exactly balance the external deforming force.
