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
