(a) Escape velocity of a body from the Earth is given by the relation:
= …. (1)
Where g = acceleration due to gravity and R = radius of the Earth
So escape velocity is independent of the mass of the body.
(b) It does not depend on the location from where it is projected.
(c) Does not depend on the direction of projection
(d) Depends on the height of the location from where the body is launched.
