. The potential energy of a particle of mass m in the gravitational field of an ob late spheroid, like Earth, is approximately k V(r) = 1 — — ²/2 ( 1₁ + ²/2 ) r where r refers to distances in the equatorial plane, k GMm as before, and 2RAR/5, in which R in the equatorial radius and AR is the difference between the equatorial and polar radii. From this, find the apsidal angle for a satellite moving in a nearly circular orbit in the equatorial plane of the Earth, where R = 4000 miles and AR = 13 miles. = .
