Quizplus · Accepted Answer

The electric potential at a point due to a point charge is given by V = kQ/r. The potential is a scalar quantity, so it adds algebraically. The positive charges contribute positively to the potential, while the negative charge contributes negatively. The net potential at point P is positive, resulting in +307 × 10^3 V.
