Solve the all parts of given problem:
Problem: Two point charges each of magnitude 1.70 µC are located on the x axis. One is at x = 1.00 m and the other is at x = -1.00 m.
Part I: Determine the electric potential on the y axis at y = 0.270 m.
_____________kV
Part II: Calculate the change in electric potential energy of the system as a third charge of +3.04 µC is brought from infinitely far away to a position on the y axis at y = 0.270 m.
