The figure below shows three small, positively charged spheres at three corners of a rectangle. The particle at upper left has a charge q₁ = 6.00 nC, the one at the lower left has a charge of q₂ = 5.00 nC, and the one at lower right has a charge q = 8.00 nC. The rectangle's horizontal side has length x = 5.00 cm and its vertical side has length y = 2.50 cm. 2₂ Ⓡ (a) What is the electric potential (in V) at the upper-right corner of the rectangle? (Assume the zero of electric potential is at infinity.) V Need Help? (b) What would be the potential (in V) at the upper-right corner if the charge q₂ at lower left was -5.00 nC instead?
