Assertion (A): A body having uniform speed in circular path has a variable acceleration.
Reason (R): Direction of acceleration is always away from the centre.
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false
Solution:
In UCM, speed is constant but velocity direction changes, so acceleration exists (centripetal). Thus (A) is true. Acceleration is towards the center, not away. So (R) is false.
