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:0400 N

D

Explanation:

The general equation for this is

F = G*m1*m2/r^2

If the distance (r) remains the same and m1 and m2 are both doubled, then the equation becomes

F1 = G * (2m1) (2m2) / r^2

F1 = 4 [G * m1 * m2) / r^2 ]

So F1 is 4 times as large as the initial Force (F)

Answer: D
