An electron is accelerating towards the left [in the negative x direction] due t

Question

An electron is accelerating towards the left [in the negative x direction] due to an electric field. Which of the following statements is correct?

A. the electric field points to the left, and the potential is higher on the right than on the left, and the electrons potential energy is higher on the right than on the left

B. the electric field points to the right, and the potential is higher on the right than on the left, and the electrons potential energy is higher on the right than on the left

C. the electric field points to the right, and the potential is higher on the right than on the left, and the electrons potential energy is higher on the left than on the right

D. the electric field points to the right, and the potential is higher on the left than on the right, and the electrons potential energy is higher on the right than on the left

E. the electric field points to the right, and the potential is higher on the left than on the right, and the electrons potential energy is higher on the left than on the right

[correct answer is D, please explain, a picture would be awesome :D]

Explanation / Answer

here ,

as the force on an negative charge is oposite to the direction of electric field

and as

Electric field = -dV/dx

electric field points in the direction of decreasing potential.

hence , for force on electron in negative x - direction.

D. the electric field points to the right, and the potential is higher on the left than on the right, and the electrons potential energy is higher on the right than on the left
