Presence of atmosphere on any planet implies that V rms <<<< V e (if V rms is equal or greater than escape velocity, then all the gases will disappear from gravitational field of planet and no atmosphere will be present).

Q. On any planet, the presence of atmosphere implies ( $C_{r m s}$ = root mean square velocity of molecules and $V_{e}$ = escape velocity)

$C_{r m s} < V_{e}$

$C_{r m s} > V_{e}$

$C_{r m s} = V_{e}$

$C_{r m s} = 0$

Presence of atmosphere on any planet implies that $V_{r m s} <<<< V_{e}$ (if $V_{r m s}$ is equal or greater than escape velocity, then all the gases will disappear from gravitational field of planet and no atmosphere will be present).

Q. On any planet, the presence of atmosphere implies (Crms​ = root mean square velocity of molecules and Ve​ = escape velocity)

Crms​<Ve​

Crms​>Ve​

Crms​=Ve​

Crms​=0
