Question

If the Earth were twice as far away from the Sun, the force of gravity attracting Earth to the Sun would be

Answer 1

1/4

Step-by-step explanation:

Fgravity is proprtional to 1 / r^2

now double r to 2r

1 / (2r)^2 = 1/4 * 1/r^2 <======this shows the force to be reduced to 1/4 of original when the distance is doubled
