Question

A space vehicle moving in a circular orbit of radius r1 transfer to a larger circular orbit of radius r2 by means of an elliptical path between A and B The transfer is accomplished by a burst of speed AV at A and a second burst of speed AV at B Then match the following R is the radius of the earth g is the acceleration due to gravity on the surface of the earth neglect the spin rotation of the earth Column I Velocity at A in a circular orbit of radius r1 B Velocity at A of elliptical orbit perihelion near point of the transferred orbit A P 9 r Column II 2812 R 1 R 281 1 1 1 C Velocity at B of elliptical orbit aphelion far point of the transferred orbit D Velocity increment at B from elliptical path s g to circular orbit R R g 12 50 1 2r 1
