The gravitational force between 2-spheres is 2.50x10 -8 power N. Their centers are 105 cm apart. The smaller sphere has a mass of 8.2 kg. Find the mass of the larger sphere.

Using Newton's Gravitational Law: F=(G*m1*m2)/d^2

where G = 6.67*10^-11 N.m^2/kg^2

by substitution: 2.5*10^-8 = (6.67*10^-11) * (8.2) *m2 / (105*10^-2)^2

therefore, m2 = 0..0504*10^-3 kg = 50.4 g
