Vedclass · Answer

(C) For a satellite to maintain a stable circular orbit around the Earth,the gravitational force must provide the necessary centripetal force.This condition is satisfied when the horizontal velocity $(V_{H})$ of the satellite is exactly equal to the critical velocity $(V_{c})$,also known as the orbital velocity.If $V_{H} If $V_{H} > V_{c}$ but less than $V_{e}$,the orbit becomes elliptical.If $V_{H} = V_{e}$,the satellite escapes the Earth's gravitational pull.Therefore,the correct condition for a stable circular orbit is $V_{H} = V_{c}$.

$A$ satellite moves in a stable circular orbit around the Earth if (where $V_{H}$,$V_{c}$,and $V_{e}$ are the horizontal velocity,critical velocity,and escape velocity respectively):
