An astronaut on the surface of a strange planet observes that the acceleration of gravity is 7 m/s².What could be an explanation of this phenomenon?

Question

Quizplus · Accepted Answer

The acceleration of gravity on a planet is determined by both its mass and radius. Option B suggests that the mass of the planet is less than that of Earth, which would lead to a smaller gravitational force. Option C suggests that the radius is bigger, which would also lead to a smaller gravitational force. Therefore, both B and C could explain the observed acceleration of gravity.
