Homework Statement
Hey guys, My prof asked us to find the radius of a cylinder within a cylindrical capacitor with 2 radii a and b. I know we use the Capacitance formula for a cylinder but I can't seem to get pass the q that shows up when I plug it into the 1/2 c*V^2
EDIT: He wants us to find a cylinder's radius that contains half the stored electric potential energy.
