Question

What does not change in the field of central force

A

Potential energy

B

Kinetic energy

C

Linear momentum

D

Angular momentum

Answer

Angular momentum

Explanation

Solution

For central force, torque is zero.

$\because \tau = \frac { d L } { d t } = 0$ ⇒ L = constant

i.e. Angular momentum is constant.
