A body was slightly displaced from its equilibrium position. Which one of the following is a condition for its stable equilibrium?

A. an increase in the kinetic energy of the body
B. an increase in the potential energy of the body
C. an increase in the potential energy of the body
D. an increase in the height of the body

Correct Answer: Option B

B. an increase in the potential energy of the body

Explanation

Stable equilibrium brings about increase in potential energy as the height rises after displacement.
