8.12** (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/dr.] (b) Show that this circular orbit is stable, in the sense that a small radial nudge will cause only small radial oscillations. Look at dUe/dr2.] Show that the period of these oscillations is equal to the planet's orbital period. UGmmea 2ur2 in2 eff(r) =-...

3. Radial Nudges and Oscillations: In your homework, you saw that for the Kepler Problem, circular orbits are stable. If you give the planet a small radial nudge, it oscillates about its original orbit with simple harmonic motion with a period equal to the orbital period. However, after deriving the conic solutions to the Kepler Problem, your professor said that the only possible trajectories are circles, ellipses, parabolas and hyperbolas. a) How...

I can do the first problem which is show the motion is
periodic. The rest questions are hard for me. I found a similar
question on the p27 of ‘mechanics’ by landau which shows on the
second picture
But I can’t understand the math. Please help.
