Homework Help: Question on electrostatic pressure

  1. May 7, 2005 #1
    I am currently working through section 2.5 of Griffiths' electrodynamics, specifically the part which deals with electrostatic pressure in conductors. I encountered the following question (question 2.39, or 2.38 in earlier versions):

    A metal sphere of radius R carries a total charge Q. What is the force of repulsion between the "northern" hemisphere and the "southern" hemisphere?

    I have an answer to the question, but I am not sure if it is right. Would anyone be willing to work through the problem, so that I can test my understanding of the subject matter?

    Any help is greatly appreciated.
