MCQ
What does not change in the field of central force
- APotential energy
- BKinetic energy
- CLinear momentum
- ✓Angular momentum
✓
Answer
Correct option: D.
Angular momentum
d
(d) For central force, torque is zero.
(d) For central force, torque is zero.
$\;\tau = \frac{{dL}}{{dt}} = 0$
$L =$ constant
i.e. Angular momentum is constant.
