Question

On Earth an object weighs 50 N. On Planet X, the object weighs 500 N. What conclusion can be drawn from these observations? A. Planet X has less mass than Earth. B. Earth has a greater diameter than Planet X. C. The acceleration due to gravity on Planet X is 98 meters per second per second. D. The acceleration due to gravity on Planet X is 500 meters per second per second.

Answer 1

The gravitation field strength of Planet X is 10 times that of Earth's, as the object weight has increased 10 times. This is only possible if the planet is more massive or more dense (smaller diameter).

Therefore, the answer is C.
