Question

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

Answer 1

Answer:

Quadruple

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
