An electron moves 4.5 m in the direction of an electric field of strength of 325n/c. determine the change in electrical potential energy associated with the electron

The change in electrical potential energy of the electron is given by:

where
e is the electron charge
is the potential difference between the initial and final point of the electron.

The electron moves by a distance d=4.5 m in the electric field of intensity , so the potential difference between the initial and final location of the electron is

where the negative sign is due to the fact that the electron is moving in the direction of the electric field, so it is moving from a point at higher potential to a point of lower potential, so the  must be negative.

Therefore, the change in electrical potential energy of the electron is

The reflection of the candle in the concave mirror formed an upside-down virtual image that is smaller than the candle.in other words. the answer is the third option, c
