Answer:
Its potential energy decreases and itselectricpotential increases.
Explanation:
The electric potential does not depend on the charge but only on the magnitude of the electric field. In particular:
- Electric potential decreases when moving in the same direction of the electric field lines
- Electric potential increases when moving in the opposite direction to the field lines
So in this case, since the electron is moving in a direction opposite to the field, the electric potential increases.
However, the electric potential energy of a charge is given by
where
q is the charge
V is the electric potential
Here we said that the electric potential is increasing: however, the charge q of an electron is negative. This means that the product (qV) is increasing in magnitude but it is negative, so the potential energy of the electron is decreasing.
