NEET Physics Question - Circular Motion

Assertion (A): In uniform circular motion, angular acceleration is zero.

Reason (R): In uniform circular motion, acceleration is constant.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

In uniform circular motion, angular speed is constant, making angular acceleration \(alpha = 0\). So (A) is true. However, linear acceleration (centripetal acceleration) continuously changes direction, so it is not constant. Thus (R) is false.
