Two stones lying on the surface of the earth have mass; a gravitationa

1.	Two stones lying on the surface of the earth have mass; a gravitational force will always exist between them. And it will try to pull the stones towards each other.But actually, we don’t see the stones moving towards each other, why? Statement 1: The acceleration because of gravitational force is in the range of 10−12ms2. Statement 2: Stones are lying on a flat surface, so they cannot move. Statement 3: The force of friction is much higher than the gravitational force. Statement 4: The stones are irregular in shape, so they cannot move. Select statements, which explains the reason for above question.
Answer» Two stones lying on the surface of the earth have mass; a gravitational force will always exist between them. And it will try to pull the stones towards each other.But actually, we don’t see the stones moving towards each other, why? Statement 1: The acceleration because of gravitational force is in the range of $10^{- 12}$ $\frac{m}{s^{2}}$ . Statement 2: Stones are lying on a flat surface, so they cannot move. Statement 3: The force of friction is much higher than the gravitational force. Statement 4: The stones are irregular in shape, so they cannot move.
