The drawing shows a square, each side of which has a length of
L = 0.250 m. Two different positive charges
q1 and q2 are fixed at the
corners of the square. Find the electric potential energy of a
third charge q3 = -7.00 x 10-9 C
placed at corner A and then at corner B.
q1= +1.50x10^-9c. q2=+4.00x10^-9c
