Question

The gravitational force between two objects is 100 N

If the mass of each object is doubled, what is the
gravitational force between the objects at the same
distance?

A) 25 N
B) 50 N
C) 200 N
D) 400 N

Answer 1

400 N

Step-by-step explanation:

F = G m1 m2 / r^2 now double the masses

F2 = G 2m1 2m2 / r^2

= 4 G m1 m2 / r^2 < ==== this is 4 times the original force

100 N * 4 = 400 N
