Subject :NSO    Class : Class 9

Which of the following is not correct?

A If we drop a 10 lb iron ball and 1 lb aluminium ball from the top of a high platform inside a mine, then both will reach the floor at the same time.
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.
