Vedclass · Answer

(B) The orbital velocity of a satellite orbiting close to the Earth's surface is given by $v_o = \sqrt{gR_e}$.If the velocity of the satellite exceeds this value,it will no longer remain in a stable circular orbit.Specifically,if the velocity reaches the escape velocity $v_e = \sqrt{2gR_e}$,the satellite will escape the Earth's gravitational pull.Therefore,for a stable circular orbit,the maximum velocity is limited by the condition where the gravitational force provides the necessary centripetal force.Thus,the maximum possible velocity for a stable orbit is $v = \sqrt{gR_e}$.

The maximum possible velocity of a satellite orbiting around the Earth in a stable orbit is
