Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I've been reviewing some general physics and came across a

problem which has stumped me. If there is anyone out ther who can

point me in the right direction, that would be greatly appreciated. The

problem is the following:

Two thin rods of length L lie along the x-axis, one between x = a/2 and

x=a/2 + L, and the other between x = -a/2 and x = -a/2 - L. Each rod has a positive charge Q distributed uniformly along the length. Show that the magnitude of the force that one rod exerts on the other is

F = (Q^2/4*pi*epsilon(0)*L^2)*ln[(a + L)^2/a(a + 2L)]
