A hollow cylindrical shell of length L and radius R has charge Q uniformly distributed along its length. What is the electric potential at the center of the cylinder?(adsbygoogle = window.adsbygoogle || []).push({});

I use eta = Q/A = Q/2piRL

dq = (eta)*dA = Q/(2piRL)*2piRdL

dV = 1 / 4 pi epsilon 0 * dq/r where r = sqrt(L^2+R^2)

V = Q/(4*pi*epsilon_0)*int(dL/(sqrt(L^2+R^2)))

This seems to be incorrect can someone tell me where I have gone wrong?

Thanks in advance.
