Electric potential is a measure of the electric potential energy per unit charge at a certain point in an electric field. It is also known as voltage and is measured in volts (V).
Electric potential can be calculated using the formula V = kQ/r, where V is the electric potential, k is a constant, Q is the magnitude of the charge at the point, and r is the distance between the point and the source of the electric field.
The point marked by a dot represents a specific location in an electric field, and the electric potential at that point can be calculated using the formula mentioned in the previous answer. This point can be used to determine the behavior of charges in the electric field.
Electric potential is a scalar quantity that represents the potential energy per unit charge at a point in an electric field, while electric field is a vector quantity that represents the force per unit charge on a test charge at a point in an electric field.
Yes, the electric potential at a point marked by a dot can be negative. This indicates that the electric field is attractive at that point, and a positive charge placed at that point would experience a force towards the source of the electric field.
