Question 418: Gravitation

Question

If $${v_e}$$ is escape velocity and $${v_o}$$ is orbital velocity of a satellite for orbit close to the earth's surface, then these are related by

Accepted Answer

Escapevelocity, $${v_e} = \sqrt {{{2GM} \over R}} $$    ...(i)
where M and R
where M and R be the mass and radius of the earth respectively. The orbital velocity of a satellite close to the earthÃ¢ÂÂs surface is
$${v_0} = \sqrt {{{GM} \over R}} $$   ...(ii)
From (i) and (ii), we get
$${v_e} = \sqrt 2 {v_0}$$

Answer

$${v_o} = \sqrt {2{v_e}} $$

Answer

vo $$=$$ ve

Answer

$${v_e} = \sqrt {2{v_o}} $$

Answer

$${v_e} = \sqrt 2 {v_o}$$
