The ratio of the radii of the planets $P_{1}$ and $P_{2}$ is $a$ . The ratio of their accelerations due to gravity is $b$ . The ratio of the escape velocities from them will be

Options:

Answer:

Solution:

$\frac{(v_{e}) p_{1}}{(v_{e}) p_{2}} = \frac{\sqrt{2 g_{1} R_{1}}}{\sqrt{2 g_{1} R_{2}}} = \sqrt{\frac{g_{1}}{g_{2}} \times \frac{R_{1}}{R_{2}}} = \sqrt{ab}$
