Question

112. Two earth satellites A and B each of mass m, are to be launched
atelites A and B each of mass m are to be launched into circular orbits about the earth's centre
R while satellite B is to orbit at an altitude equal
Satellite A is to orbit at an altitude equal to the radius of earth wine
to 3R. Then (if M is the mass of earth)
(1) the ratio of potential energy of satellite A to that of satellite B in orbit is 1:2.
(2) the ratio of potential energy of satellite B to that ofsatellite A in orbit is 1:2
GMm
(3) the total energy of A is greater than the total energy of B by 8
(4) the ratio of the kinetic energy of satellite A to that of satellite B in orbit is 1:2.
