Question

At what time is the centripetal acceleration zero?

Answer 1

Answer:

Component of change in velocity in uniform circular motion is zero so there is no tangential acceleration. Circular motion is special kind of curvilinear motion whose radius of curvature is constant with time.

hope you get it...
