Two equal masses of 5 kg each are 2m. What is the gravitational force between them?

Question

please explain the answer.Wait... i have another question.

Two identical objects are separated by a distance of 1m. If the gravitational force with them is 6.67x10 raised to the power of -9 newtons. What is the mass of each object?

Answer 1

part 1,

Gravitational force = Gmm/r^2

=6.67 x 10^-11 x 5^2 / 2^2

=4.17 x 10^-10 N

part 2,

6.67x 10^-9 = GM^2/1^2

M = 10kg
