Two charged point-like objects are located on the x-axis. The point-like object with charge q1 = 3.80 µC is located at x1 = 1.25 cm and the point-like object with charge q2 = -2.44 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).
