m = mass of each point mass = 1 kg
F = gravitational force of attraction between the two masses = 10⁻¹⁰ N
r = distance between the two point masses = ?
G = universal gravitational constant = 6.67 x 10⁻¹¹
gravitational force of attraction between the two masses is given using newton's law gravitation as
F = G m²/r²
inserting the values in the equation
10⁻¹⁰ = (6.67 x 10⁻¹¹) (1)²/r²
r = 0.82 m
