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 2.50 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 a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units. va v a = nothing nothing request answer part b what is the electric potential at point b? express your answer with the appropriate units. vb v b = nothing nothing request answer part c a point charge q3 = -2.00 μc moves from point a to point b. how much work is done on q3 by the electric forces exerted by q1 and q2? express your answer with the appropriate units. wab w a b = nothing nothing request answer
