Answer : Option A
Explanation :
Uniform circular motion occurs when a body moves in a circular path with constant velocity. The acceleration of a body experiencing uniform circular motion is always directed toward the center of the circle (centripetal acceleration or
ac = V2 / r
where v is the body’s velocity, and r is the radius of the circle). This acceleration is constant in magnitude but changes in direction, so, it is variable at every point of the circular path.
