Escape speed- ve-x221A-2gR

The ratio of escape velocities of two planets if $g$ values on the two planets are $9.9$ m/s $^{2}$ and $3.3$ m/s $^{2}$ and their radii are $6400 k m$ and $3400 k m$ respectively is
$2.36 : 1$
$1.36 : 1$
$3.36 : 1$
$4.36 : 1$

Escape speed, $v_{e} = \sqrt{2 g R}$

The ratio of escape velocities of two planets if g values on the two planets are 9.9 m/s2 and 3.3 m/s2 and their radii are 6400km and 3400km respectively is2.36:11.36:13.36:14.36:1

Escape speed, ve=√2gR

The ratio of escape velocities of two planets if $g$ values on the two planets are $9.9$ m/s $^{2}$ and $3.3$ m/s $^{2}$ and their radii are $6400 k m$ and $3400 k m$ respectively is
$2.36 : 1$
$1.36 : 1$
$3.36 : 1$
$4.36 : 1$

Escape speed, $v_{e} = \sqrt{2 g R}$
