Question

Quizplus · Accepted Answer

The force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. Therefore, if the masses of the Sun and Earth each were doubled, the force of gravity between them would increase by a factor of 4 (2 x 2), since the masses in the equation have doubled.
