Question

An electron is placed at a position on the x-axis where the electric potential is + 10 V. Which idea below best describes the future motion of the electron?
(a) The electron will move left (-x) since it is negatively charged.(b) The electron will move right (+x) since it is negatively charged.(c) The electron will move left (-x) since the potential is positive.(d) The electron will move right (+x) since the potential is positive.(e) The motion cannot be predicted with the information given.

Answer 1

Answer:

option (e)

Explanation:

As the electron is placed at a point where the potential is  + 10 V. electrons moves from lower potential to higher potential, so we cannot predict the direction of motion because we don't have any information about the potential at other point.

So, option (e) is correct.
