## Homework Statement

two identical point charges are on diagonally opposite corners of a square that is 0.5m on a side. Each charge is +3 x 10^ -6 C. How much work is done by the electric force when 1 charge moves to an empty corner?

## Homework Equations

W= u= qV = q(kq/r) = kq^2/ r (is this right??)

## The Attempt at a Solution

w= kq^2 / r = (k)(+3 x 10^ -6)^2 / (.5)

the real answer is -4.7 x 10^-2 but i don't know how to get that. thanks
