“Electric potential at any point in a electric field is equal to the ratio of the work done in bringing a test charge from infinity to that point, to the value of test charge.” Suppose, W be the work required in bringing a test charge q0 from infinity to a point b against the repulsive force F acting on it, then potential at the point b is
Since, W and q0 both are scalar quantities, the potential is also a scalar quantity.
