The figure below shows three small positively charged beads at three corners of a rectangle The particle at upper left has a charge q 6 00 nC the one at the lower left has a charge of q2 4 00 nC and the one at lower right has a charge 43 3 00 nC The rectangle s horizontal side has length x 5 00 cm and its vertical side has length y 3 50 cm 9 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 q at lower left was 4 00 nC instead V
