The gravitational force between two bodies of masses m1 and m2 separated by distance r is F. State the effect on the gravitational force when m1 increases twice.

• 2F

• 1/2 F

• 4F

• 4F

Answer explanation

G(2m₁)(m₂)=same as G*2*m*m = 2* (Gmm)=2F

What happens to Gravitational force if I double both of the masses but don't change their distance?

• doubles

• half as big

• 4x bigger

• 4x smaller

Answer explanation
