The escape velocity of a body form the earth depends on
(i) the mass of the body.
(ii) the location from where it is projected.
(iii) the direction of projection.
(iv) the height of the location form where the body is launched.

A

(i) and (ii)

B

(ii) and (iv)

C

(i) and (iii)

D

(iii) and (iv)

Text Solution

Verified by Experts

The correct Answer is:
B
(b) The escape velocity is independent of mass of the body and the direction of projection. It depends upon the gravitational potential at the point from where the body is launched. Since this potential depends slightly on the latitude and height of the point, the escape velocity depends slightly on these factors.
