b. 51 kV
c. 76 kV
d. 64 kV
e. 13 kV

Question 2

Three charged particles are positioned in the xy plane: a 50-nC charge at y = 6 m on the y axis, a -80-nC charge at x = -4 m on the x axis, and a 70-nc charge at y = -6 m on the y axis. What is the electric potential (relative to a zero at infinity) at the point x = 8 m on the x axis?
a. +81 V
b. +48 V
c. +5.8 V
d. -72 V
e. -18 V
