Question

The figure below shows three small, positively charged spheres
at three corners of a rectangle. The particle at upper left has a
charge *q*_{1} = 6.00 nC, the one at the lower left
has a charge of *q*_{2} = 7.00 nC, and the one at
lower right has a charge *q*_{3} = 3.00 nC. The
rectangle's horizontal side has length *x* = 5.50 cm and its
vertical side has length *y* = 3.50 cm.

Three positive charges lie at three of the corners of a
rectangle of horizontal side length *x* and vertical side
length *y* < *x*.

- An charge labeled
*q*_{1}is at the upper left corner. - A charge labeled
*q*_{2}is at the lower left corner. - A charge labeled
*q*_{3}is at the lower right corner.

(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*_{2} at lower left was

−7.00

nC instead?

V
