1. The problem statement, all variables and given/known data A wire that has a uniform linear charge density of 2.2 μC/m is bent into the shape as shown below, with radius 3.7 m. The Coulomb constant is 8.98755 × 109 N · m2/C2. Find the electrical potential at point p. Here is the image: http://s769.photobucket.com/albums/xx339… [Broken] (Radius is 3.7 and the distance of line is 7.4) Answer in units of V. 2. Relevant equations V = - integral (E dl) 3. The attempt at a solution I am at a total loss as to how to solve this. First I thought that since the density is uniform, we won't have to integrate. But I am guessing that integration will be done on this one first for the line and then for the circle. But I am totally stuck as to what to integrate, and what will be the limits of integration. On this one I spent about 1 hour, but I have reached to no conclusion. I need help on this one! :) PLEASE HELP!!! :) Thanks!
