What is the difference in orbital velocity between Saturn's two coorbital satellites if the semimajor axes of their orbits are 151,400 km and 151,500 km?

If you were to record the spectrum of Saturn as well as the A ring, you would find light from one edge of the rings redshifted and light from the other edge blueshifted. If you observed a spectral line
at a wavelength of 480 nm, what difference in wavelength (in nm) should you expect between the opposite edges of the rings? (Hints: The radius of the edge of the A ring is 136,500 km. Use the
formula for orbital velocity, V.
V
GM
and the formula for Doppler shift,
V,
nm
