A ring of charge with radius R = 2.5 m is centered on the origin
in the x-y plane. A positive point charge is located at the
following coordinates: x = 17.1 m y = 3.8 m z = -16.3 m The point
charge and the total charge on the ring are the same, Q = +81 C.
Find the net electric field along the z-axis at z = 4.5 m.
