The gravitational force acting on a particle of 1 g , due to a similar particle is equal to 6 . 67 × 10 - 17 N . Calculate the separation between the particles.

F = G m 1 m 2 r 2 , where G is universal gravitational constant, m 1 and m 2 are masses of two bodies. For above case m 1 = m 2 = 1 g = 10 - 3 kg G = 6 . 67 × 10 - 17 m 3 kg - 1 s - 2 Putting the given values, we get, 6 . 67 × 10 - 17 = 6 . 67 × 10 - 11 × 10 - 3 × 10 - 3 r 2 ⇒ r = 1 m
