If the distance between two objects is doubled, what happens to the gravitational force between them?

Question

a
it decreases to 1/2 of its original value
b
it decreases to 1/4 of its original value
c
it stays the same
d
it doubles

Answer 1

b. it decreases to 1/4 of its original value. This relationship is described by the inverse square law of gravity, which states that the force of gravity between two objects decreases as the square of the distance between them increases. Doubling the distance would result in a four-fold increase in the denominator of this equation, resulting in a 1/4 decrease in the force of gravity.
