MCQ
For a particle in circular motion the centripetal acceleration is
- ALess than its tangential acceleration
- BEqual to its tangential acceleration
- CMore than its tangential acceleration
- ✓May be more or less than its tangential acceleration
✓
Answer
Correct option: D.
May be more or less than its tangential acceleration
d
(d)There is no relation between centripetal and tangential acceleration. Centripetal acceleration is must for circular motion but tangential acceleration may be zero.
