Question

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 $45^\circ$ with the vertical, the escape velocity will be

• A. $11 \sqrt {2} \, km/s$
• B. $22\,km/s$
• C. $11\,km/s$
• D. $11 / \sqrt{2}\, m/s$

Answer 1

Answer: (C)

$11\,km/s$

Answer 2

The escape velocity of a body is independent of the angle of projection.
