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
a decrease in the kinetic energy of the body
D
an increase in the height of the body
Verified Correct Answer: B.
Physical Principles & Numerical Solution
