The gravitational force is a force that attracts any object with mass. We use the equation as follows:
F = Gm1m2 / r^2
where G is the gravitational constant that is equal to 6.67408 × 10-11 m3 kg-1 s-2, m is the mass and r is the radius.
2.5x10^-2= 6.67408 × 10^-11(3)m2 / 6300^2'
m2 = 4.96 x 10^15 kg
