The escape velocity for a body projected...

The escape velocity for a body projected vertically upwards from the surface of earth is 11 km/s. If the body is projected at an angle of `45^(@)` with the vertical, the escape velocity will be

A

`11sqrt2`km/s

B

22km/s

C

11 km/s

D

`11/sqrt2` km/s

Text Solution

Verified by Experts

The correct Answer is:
C
Work is done against gravitational force, which is a conservative force. Therefore, the escape velocity is independent of the angle of projection.
