If an electron is released from rest in a uniform electric field, the electric potential energy of the charge-field system (a) increases, (b) decreases, or (c) remains the same. Explain. The field exerts a force on the electron, causing it to accelerate in the direction opposite to that of the field.The electric field points in the direction of the force that would be on a positive charge. An electron will move in the opposite direction of the electric field because of its negative charge. Therefore it will move toward the left.
