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. $11\sqrt{2}km{s}^{-1}$
• B. $22km{s}^{-1}$
• C. $11km{s}^{-1}$
• D. $\frac{11}{\sqrt{2}}km{s}^{-1}$

Answer 1

The correct option is C $11km{s}^{-1}$

Escape speed does not depend on the angle of projection
