SUMMARY
The electric potential at a specific point, as indicated by a dot in the provided figure, can be calculated using the formula V = k * q / r, where V is the electric potential, k is Coulomb's constant, q is the charge, and r is the distance from the charge to the point. The discussion clarifies that electric potential is a scalar quantity, meaning vectors and angles are not necessary for this calculation. When multiple point charges are present, their potentials can be summed to find the total electric potential at the point of interest.
