Question

14. Two point charges are located on the y-axis. One is at

y = 1.00 m,

the other is at

y = −1.00 m,

and they both have a charge of

q = +1.80 µC.

(a)

Determine the electric potential (in kV) on the x-axis at

x = 0.320 m.

kV

(b)

Calculate the change in electric potential energy of the system (in J) as a third point charge of −3.10 µC is brought from infinitely far away to a position on the x-axis at

x = 0.320 m.

J
