point charges on q1=+2.00uc and Q2=-2.00ic are placed at adjacent corners of a sqaure for which the lengt of a=each side is 3.00cm. point a is at the center of the square and point b is at the empty corner closets to q2. take the electric potential to be zero at a distance far from both charges,=. 9a0 what is the electric potential at point a due to q1 and q2? (b) what is the electric potential at point b? (c). a point charge q3=-5.00uc moves from point a to point b. how much work is done on q3 by the electric forces exerted by q1 and q2? is this work positive or negative?
