The radius of a planet is twice the radius of earth. Both have almost equal average mass-densities. If $\displaystyle V_{\mathrm{P}}$ and $\displaystyle V_{\mathrm{E}}$ are escape velocities of the planet and the earth, respectively, then :
Official answer
(4)
$\displaystyle V_{\mathrm{P}}=2 V_{\mathrm{E}}$
