Hi there!
Using Newton's Law of Universal Gravitation:

Fg = Force of gravity (N)
G = Gravitational Constant
m₁ = mass of object 1 (kg)
m₂ = mass of object 2 (kg)
d = distance between the objects (m)
There is a direct relationship between the masses of the objects and the resulting force of gravity, so we can plug new values in:

Thus, the correct answer is J. 10Fg.
