Question 402: 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

v
o
$=$ v
e

Answer

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

Answer

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