When solving for the electric field of a cylinder with a radius R and a charge density p, how do you find the electric field inside the cylinder as just a function of r and R? I thought that Q(enc) becomes p(pi*r^2*L/pi*R^2*L) but then the left hand side still has E2rpiL which means the final electric field equation still has L in it. How do I get rid of the L?
