Griffiths 2.26 E&M

    This problem is finding the potential difference between the vertex (a) and the center of the top (b), for a cone with height and radius H. Can this problem be done by: finding the potential at (b) using a flat disc and then finding the potential at (a) using the surface area of a cone (without the disc). When I do this I get a potential at b = 2(pi)*sigma*h. I then find the potential at the vertex = (pi)*sigma*H*ln(1+sqrt(2)). This solution is almost exact as the one I have seen online, except my potential for the vertex is a factor of 2 off. I have used Gaussian units.
