Which of the following is not correct?

B The gravitational force of attraction between the two bodies increases when their masses are increased and distance is reduced.
C We do not observe small objects moving towards each other because frictional force balances the gravitational pull.
D When a body is thrown up, the acceleration due to gravity at the topmost point is zero because velocity of the body is zero.
