1.	Regarding pure rolling motion of a spherical body of radius R shown, the correct statement(s) are
Answer» When a rigid body rolls, without slipping on a horizontal SURFACE a point on its circumference moves along a curved path called cycloid. The distance covered by the point 'O' on the circumference of the rolling object along the cycloid is 8R in ONE REVOLUTION. The distance moved by the center of mass in one revolution is `2piR` The distance moved by the centre of mass in one revolution is less than `2piR` Answer :A::B::C
