A satellite is following an elliptical orbit around earth. Its engines are capable of providing a one time impulse of a fixed magnitude. In order to maximize energy of satellite the impulse should be given :- (A) Along satellite's velocity when satellite is at perigee (B) Along satellite's velocity when satellite is at appogee (C) Away from earth, when satellite is at perigee (D) Away from earth, when satellite is at apogee
