Planets A and B move in circular orbits at different distances from a star of mass M. Planet A has mass
m_(0) and orbital radius r_(0). The gravitational potential energy of the Planet A-star system is U_(A). Planet B
has mass 4m_(0) and orbital radius 2r_(0). The gravitational potential energy of the Planet B -star system is U_(B)
What is the ratio U_(A):U_(B) ?
