Question

If the distance between Earth and the Sun were cut in half, the gravitational force between these two objects would:

Answer 1

Quadruple

Step-by-step explanation:

See attachment.

The force is dependent on 1/r^2. if the new d is 1/2 r, the force would quadruple: ((1/2)r)^2 = (1/4)r^2

F1 = G(m1m2)/r^2

F2 = G(m1m2)/(1/4)r^2 or 4G(m1m2)/r^2

F2 = 4F1
