The escape velocity from the earth is `11.2km//s`. If a body is to be projected in a direcion making an angle `45^(@)` to the vertical, then the escape velocity is

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.
