Question

________ does not affect the escape velocity of an object.

• A. The Earth's mass
• B. The Earth's radius
• C. The mass of the object
• D. None of the above

Answer 1

The correct option is C The mass of the object

The escape velocity of any object is constant for earth, and is given by:
${\text{v}}_{\text{esc}}=\sqrt{\frac{2\text{GM}}{\text{R}}}$, where the terms have their usual meanings.
The escape velocity of Earth is equal to $11.2{\text{km s}}^{-1}$. So, irrespective of the object's mass, every object has the same escape velocity.
