2. Consider the charges in the image below. (Same setup as previous problem.) (The z-axis is pointed out of the page.) The distances on the grid lines are measured in

cm.The charge in the lower right is a negative charge. The two charges on the left are positive charges. Each pictured charge has a magnitude of |q| = 5 x 10^-9 C. (a) Find the electric potential at the points (i) (х, у, 2) %3D (0, 0, 0) cm (ii) (х, у, 2) = (3,4,0) cm (iii) (x, y, z) = (0, 0, 5) cm (iv) (х, у, 2) 3 (-3,0, 0) cm (v) (х, у, 2) 3 (0, —4,0) сm (The electric potential at a point at infinity is V(oo) = 0 V.)
