Electricity and Magnetism in a Thundercloud

  1. Nov 27, 2007 #1
    Magnetism and Potential Energy

    1. The problem statement, all variables and given/known data

    2. Relevant equations


    3. The attempt at a solution
    I have a start on the questions:
    (a) Down
    (b)i. Down
    ii. Equal because the distance does not matter because they are on equipotential lines.
    (c) I don't understand the question very well, but I said it was 0
    (d) U=[tex]\frac{8.99x10^{9}*30*-30}{3}[/tex] = 2.697x10[tex]^{12}[/tex]
    (e) 0

    I hope you guys can help me out.
