Question

Escape velocity on the earth

• A. Is less than that on the moon
• B. Depends upon the mass of the body
• C. Depends upon the direction of projection
• D. Depends upon the height from which it is projected

Answer 1

The correct option is D

Depends upon the height from which it is projected

We know, Escape velocity is given by $V=\sqrt{\frac{2GM}{\left(R+h\right)}}$

Where $V$ is the escape velocity

$G$ is the universal gravitational constant

$M$ is the mass of the body to be escaped from

R is the distance from the center of the mass

h is the height

Therefore, the escape velocity depends on the height from which it is projected.

Hence, the correct option is (D).
