The Figure Below Shows Three Small Positively Charged Beads At Three Corners Of A Rectangle The Particle At Upper Left 1 (36.34 KiB) Viewed 42 times

The figure below shows three small, positively charged beads 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 92 = 4.00 nC, and the one at lower right has a charge 93 = 5.00 nC. The rectangle's horizontal side has length x = 6.50 cm and its vertical side has length y = 2.50 cm. 9₁ X 2₂ 9₂ i (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 (b) What would be the potential (in V) at the upper-right corner if the charge 92 at lower left was -4.00 nC instead? V + y
