Quick Coulomb's Law Question

If I have a positive and negative charge, say -1C and +1C, will the force of attraction be the same as the force of repulsion for a +1C and a +1C charge?

I've been trying to teach this electrostatics chapter to myself before term commences so I can get a bit of a head start.

Yes. (Assuming the charges are the same distance apart, of course.) The force is given by Coulomb's law.

Try plugging some values in to the equation for the force of electrostatic repulsion/attraction and see what happens =]
