RE-NEET 2024 Physics Escape Velocity MCQ Question with Solution

The escape velocity for earth is $v$ . A planet having 9 times mass that of earth and radius, 16 times that of earth, has the escape velocity of:

A

$\frac{v}{3}$

B

$\frac{2v}{3}$

C

$\frac{3v}{4}$

D

$\frac{9v}{4}$

Correct Answer

Option C

Detailed Explanation

Escape velocity $v_e$ is given by $v_e = \sqrt{\frac{2GM}{R}}$ . For the new planet, $v_e = \sqrt{\frac{2G(9M)}{16R}} = \frac{3v}{4}$ .
