A particle of mass m is projected from the satellite in a forward direction with a velocity v = 2/3 times the orbital velocity (this velocity is given w.r.t. earth). During subsequent motion of the particle, its minimum distance from the centre of earth is $\frac{r}{2}$ r $\frac{22r}{3}$ $\frac{4r}{5}$
