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:0400 N

Answer 1

D

Step-by-step 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
