NEET 2024 Physics Acceleration due to Gravity MCQ Question

Type: MCQ-conceptual-Easy-Class 11

The mass of a planet is ¹⁄₁₀th that of the earth and its diameter is half that of the earth. The acceleration due to gravity on that planet is:

A

4.9 m s⁻²

B

3.92 m s⁻²

C

19.6 m s⁻²

D

9.8 m s⁻²

Correct Answer

Option B

Detailed Explanation

The acceleration due to gravity is given by g=GMR2g = \frac{GM}{R^2}. Since the mass is 110\frac{1}{10} and radius is 12\frac{1}{2}, the acceleration is 110×41=25\frac{1}{10} \times \frac{4}{1} = \frac{2}{5} of earth's gravity, which is 4.9 m s⁻².
