Point charges q1=+2.00μC and q2=−2.00μC are placed at adjacent corners of a square for which the length of each side is 4.50 cm . Point a is at the center of the square, and point b is at the empty corner closest to q2. Take the electric potential to be zero at a distance far from both charges. Part AWhat is the electric potential at point a due to q1 and q2?Part BWhat is the electric potential at point b?Part CA point charge q3 = -4.00 μC moves from point a to point b. How much work is done on q3 by the electric forces exerted by q1 and q2?
