a) By examining the effective potential energy (8.32) find the radius at which a planet (or comet) with angular momentum can orbit the sun in a circular orbit with fixed radius. [Look at dUeff I dr 1 (b) Show that this circular orbit is stable, in the sense that a small radial nudge will cause only s
