A satellite revolving roung the earth with orbital speed $v_0$, If it stops suddenly, the speed with which it will strike the surface of the earth would be (-ve escape velocity of the particle on earth's surface)

Question

$$(a)\;\frac{v_e^2}{v_0} \quad (b)\; v_0 \quad (c)\;\sqrt {v_e^2-v_0^2} \quad (d)\;\sqrt {v_e^2-2 v_0^2}$$
