The gravitational force acting on a particle of 1g due to a similar particle is equal to 6.67 × 10–17 N. Calculate the separation between the particles.

Given -


Mass of the particle, m = 1 g



Let the r be the distance between the particles .
Gravitational force between the particles,


We know that gravitational force existing between the particles is given by



Where,


G = universal gravitation constant =


m1 =mass of first object,


m2 = mass of second object


r = distance between the objects


Substituting the values in the above formula-





Hence, the separation between the particles is 1 m
