4.The work done by a
centripetal force acting on an object moving at a constant linear speed is:
I. zero because the centripetal force is perpendicular to the displacement of the object.
Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
