I am not sure if this is the right forum for this but I believe it is the closest to the question I would like an answer to.

I would like to calculate the electrical force between Mars and the Earth. I believe I understand that in order to do this, I must apply Coulomb's law:

E= Q*q/(4*pi*e0*r^2)

where Q equals the point charge of the Earth, q equals the point charge of Mars, e0 equals the permittivity of vacuum constant, and r^2 equals the distance between the two.

Assuming I know the distance between the Earth and Mars, how would I go about calculating the point charges of the Earth and Mars? Just thinking about it makes my head hurt!

I figured I'd swallow my pride and ask people who know a whole lot more than I do. I believe I have the right equation as well.

Please help!

Thank you,
