A body is moving on a rough horizontal table in a circular path being tied to a nail by a string. While the body is in motion, match the quantities in column-A with their description in column-B.

Due to frictionat=μg (Kinetic friction will act opposite to velocity)ar=v2R(a) Magnitude of ar changes because speed changes so magnitude and direction (always remaining towards centre) both changes.(b) Kinetic friction is constant in magnitude but direction is opposite to velocity.(c) Angular momentum decreases in magnitude but remains in same direction.(d) N remains constant in magnitude and direction.
