Homework Help: physics

Posted by Shelly on Sunday, March 23, 2008 at 12:47pm.

A charge of -2q is placed a distance r from the origin and a charge of +2q is placed a distance 2r from the origin. What is the amount of work needed to move a charge of q to the origin from infinity?

I don't get the question. And please explain to me how can I do it.
