Question

In an equilibrium state of a solid, what is the condition of net force on each constituent?

Options

• The net force is always positive

• The net force is zero

• The net force equals the applied external force

• The net force cannot be determined

Answer 1

The net force is zero

Explanation:

The constituent atoms/molecules are arranged such that the net force on each is zero. This stable condition is disrupted when an external deforming force is applied.
