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 3.50 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.
A point charge q3 = -5.00 μC moves from point a to point b. How
much work is done on q3 by...

Three charges are at three corners of a rectangle with

potential (V) at the fourth corner? (Please note: the charge
is given in micro-Coulomb.)
