Vedclass · Answer

(C) The escape velocity $(v_e)$ is given by the formula $v_e = \sqrt{2gR}$.The orbital velocity $(v_o)$ of a satellite orbiting close to the surface is given by $v_o = \sqrt{gR}$.By comparing these two equations,we get the relation $v_o = \frac{v_e}{\sqrt{2}}$.Given that $v_e = 2 \, km/s$,we substitute this value into the relation:$v_o = \frac{2}{\sqrt{2}} = \sqrt{2} \, km/s$.Therefore,the correct option is $C$.

The value of escape velocity on a certain planet is $2 \, km/s$. Then the value of orbital speed for a satellite orbiting close to its surface is
