What would become of the earth's orbit (which you may consider to be a circle) if half of the sun's mass were suddenly to disappear? would the earth remain bound to the sun? [hints: consider what happens to the earth's ke and pe at the moment of the great disappearance. the virial theorem for the circular orbit (problem 4.41) with this one.] treat the sun (or what remains of it) as fixed.
