STANDARD Physics Escape Velocity Multiple Correct Question
Type: Multiple Correct-conceptual-Medium-Class 11
The escape velocity of a body from 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 from where the body is launched.
A
(i) and (ii)
B
(ii) and (iv)
C
(i) and (iii)
D
(iii) and (iv)
Correct Answer
Option B
Detailed Explanation
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 on these factors.
