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

Your rearrangement is correct, also.
