Assertion: Centripetal acceleration is a...

Assertion: Centripetal acceleration is always directed towards the center of rotation of an object undergoing uniform circular motion.
Reason: Centripetal acceleration is a constant vector.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Centripetal acceleration ` = (v^(2))/( R)`
For uniform circular motion, v and R are constant, the magnitude of the centripetal acceleration is constant. But the direction changes-pointing always towards the centre. Therefore, a centripetal acceleration is not a constant vector.
