How much would the force of Earth's gravity at its surface differ if the Earth's volume were increased 125 times while its mass was increased 25 times?
A) 25 times less
B) 25 times larger
C) no difference
D) 125 times less

Quizplus · Accepted Answer

The force of gravity at Earth's surface is determined solely by its mass and radius, not its volume. Increasing the volume without changing the mass or radius would have no effect on the force of gravity. Therefore, the force of gravity would not differ if the Earth's volume were increased 125 times while its mass was increased 25 times.
