The formula for calculating electric potential at a point P is V = kQ/r, where V is the electric potential, k is the Coulomb's constant, Q is the charge creating the electric field, and r is the distance from the charge to the point P.
The unit used to measure electric potential is volts (V).
The electric potential at point P is inversely proportional to the distance from the point charge. This means that the electric potential decreases as the distance from the point charge increases.
Yes, the electric potential at point P can be negative if the charge creating the electric field is negative. It can also be negative if the point P is located in the opposite direction of the electric field.
Yes, the electric potential at point P can be zero if the point P is located at an infinite distance from the charge creating the electric field. It can also be zero if the point P is located on an equipotential surface, where the electric potential is constant.
