Since 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 10-12m/s2Statement 2: Stones are lying in a flat surface, so they cannot moveStatement 3: The force of friction is much higher than gravitational force. Statement 4: The stones are irregular in shape, so they cannot move |
