The figure below shows three positively charged particles at three corners of a rectangle. The particle at upper left has a charge q1 = 8.00 nC, the one at the lower left has a charge of q2 = 7.00 nC, and the one at lower right has a charge q3 = 4.00 nC. The rectangle's horizontal side has length x = 5.00 cm and its vertical side has length y = 2.50 cm. What is the electric potential (in V) at the upper-right corner of the rectangle? (Assume the zero of electric potential is at infinity.)What would be the potential (in V) at the upper-right corner if the charge q2 at lower left was −7.00 nC instead?
