Question

The escape velocity for an object to leave the surface of the earth does not depend on its size, shape, mass or direction of projection of the body.

(a) True

(b) False

I got this question during a job interview.

I want to ask this question from Gravitation topic in section Gravitation of Physics – Class 11

Answer 1

Right answer is (a) True

Explanation: The escape velocity for any object on earth is approximately constant at all points on the earth’s surface, i.e., the escape velocity of earth is approximately equal to 11.2 km/s and is not determined by any parameter of the projectile.
