Vedclass · Answer

(B) In uniform circular motion,a body moves along a circular path with a constant speed. Although the speed is constant,the direction of velocity changes at every point,which implies that the body is accelerating. This acceleration is known as centripetal acceleration,which is directed towards the center of the circle. According to Newton's second law of motion $(F = ma)$,the net force acting on the body must be in the same direction as the acceleration. Therefore,the net force (centripetal force) is directed towards the center of the circle,which is always perpendicular to the instantaneous velocity (direction of motion). Since the speed $(v)$ and the radius $(r)$ are constant,the magnitude of the centripetal force $(F = mv^2/r)$ remains constant.

The net applied force on a body in uniform circular motion should always be
