    Cause of Gravity? - Uncovering the Mysteries of Physics

    Personally, I don't know of physicists who reject the validity of a new model simply because it has yet to be tested (as opposed to it being fundamentally untestable). Things like string theory get a lot of flack, in my humble opinion, simply because people become so enraptured with the...

    Electric Potential of Uniformly Charged Cone

    That did it! Thanks so much, guys; I'd been sitting on this problem for over a day. For anyone else who, like me, got stumped by the math of this problem, here's a recap: 1. Complete the square of the denominator. You will have one squared term containing r and another with just a constant. 2...

    Electric Potential of Uniformly Charged Cone

    Thanks so much for the quick replies. I'll convert my work to LaTeX and post it up shortly, but since you mentioned it, is there a more straightforward way to do the integral that you suggest I try? It surprises me that this has taken me so much effort considering that it's not even one of the...

    Electric Potential of Uniformly Charged Cone

    Ah, I think I understand what you're saying... but I'm still not getting the answer I expect. I broke up the integral into two integrals (one from 0 to \frac{h}{\sqrt{2}} and the other from \frac{h}{\sqrt{2}} to h \sqrt{2}, but when I work this out and use the new limits of integration, I end up...

    Electric Potential of Uniformly Charged Cone

    Hm, I don't think I follow... Since the square root is defined to be positive, how do I justify putting a negative in front?

    Electric Potential of Uniformly Charged Cone

    [SOLVED] Electric Potential of Uniformly Charged Cone I'm actually a senior in physics graduating this year, but wanted to review some E&M before grad school in the fall. I was apparently never assigned this problem during my sophomore year, but it's from Griffiths. I'm also aware that this has...
