B) burrow deep inside the planet.
C) both of these
D) none of these

Question

Quizplus · Accepted Answer

The force of gravity acting on you increases if you stand on a planet with a shrinking radius because gravity's strength is inversely proportional to the square of the distance from the center of mass. As the radius decreases, you are closer to the planet's center, increasing gravitational force. Burrowing deep inside the planet actually decreases the force of gravity acting on you, as you would be affected by less mass beneath you in accordance with the shell theorem.
