Two charged point-like objects are located on the x-axis. The point-like object with charge q1 = 4.60 µC is located at x1 = 1.25 cm and the point-like object with charge q2 = −2.14 µC is located at x2 = −1.80 cm. A) Determine the total electric potential (in V) at the origin.

B) Determine the total electric potential (in V) at the point with coordinates (0, 1.50 cm).
