Question

The escape velocity of a body projected vertically upwards from the surface of the earth is 'v' if the body is projected at an angle of ${30}^o$ with the horizontal, the escape velocity would be

• A. $\frac{v}{2}$
• B. $\frac{sqrt3}{2}v$
• C. $2v$
• D. $v$

Answer 1

The correct option is D $v$

Escape velocity $V_e=\sqrt{2gR}$ is independent of the projection angle. So, the escape velocity will be $v$.
