NEET Physics Question - Circular Motion - Non Uniform Circular Motion

Assertion (A): The equation of motion can be applied only if the acceleration is along the direction of velocity and is constant.

Reason (R): In circular motion, if velocity is constant then its motion is called uniform circular motion.

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:

Equations of motion (kinematic equations) are for constant acceleration, irrespective of its direction relative to velocity. So (A) is false. In uniform circular motion, speed is constant, but velocity (a vector) continuously changes direction, hence it is not constant. So (R) is false. Both are false.
