Question

A uniformly-charged wire of total charge Q, and total length L=6.4 m is placed as shown in the figure, where the left end is at a distance a=0.1 m from the origin.
Another point charge Q is placed at the right end of the wire. If E1 and E2 are the magnitudes of the electric field at the origin by the wire and by the charge,
respectively, then find the ratio E1/E2.

A negative point charge Q1, is located at the origin. A rod of length L is located along the x axis with the near side a distance d from the origin. A positive charge Q2, is uniformly spread over the length of the rod. After integrating the force from each slice over the length of the rod, the magnitude of the electric force on the charge at the origin can be represented as the following: F = (k |Q1| |Q2|) / (d (d + L)) Let L = 2.22m, d = 0.42m, Q1 = -6.29µC, and |Q2| = 11.1µC.
