The acceleration due to gravity at the Earth's surface depends on
- A. its mass only.
- B. its radius only.
- C. both its mass and radius. ✓
- D. either its mass or its radius.
Correct Answer: C. both its mass and radius.
Explanation
The acceleration due to gravity on the surface of the Earth is given by the formula g = \frac{GM}{R^2}, meaning it depends on both the Earth's mass (M) and its radius (R).
