Question

The escape velocity from the surface of a planet is independent of:
Options
A The mass of the planet.
B The radius of the planet.
C The mass of the object escaping.
Correct Answer
D The gravitational constant G.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The formula for escape velocity is v_e = √(2GM/R). It depends on the planet's mass M and radius R, and G. It does not depend on the mass m of the object being launched.

Hint

Look at the derived formula v_e = √(2GM/R) or v_e = √(2gR). Is the object's mass present?
