Homework Help: Rearranging Coulombs Law

  1. Jun 3, 2007 #1
    Coulombs law is


    F = (1 / (4*pi*epsilon))*((q*Q)/r^2)


    I want to rearrange this so that Q is the subject. Will I be right in thinking that the equation should read


    Q = 4*pi*F*epsilon * (r^2/q)

    Many thanx

    By the way, what kind of package would I need to import my equations onto this board? I think it would make things a lot easier to read

    LaTeX is the program used to write equations in a thread on PF.

    Your rearrangement is correct, also.
