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
Options
- A11 2 ~km / s
- B22 ~km / s
- C11 ~km / s
- D11 2 ~km / s
Correct answer
C. 11 ~km / s
Step-by-step solution
Escape velocity of a body is independent of the angle of projection. Hence, changing the angle of projection is not going to effect the magnitude of escape velocity
