In a certain region of space, the electric potential is zero everywhere along the x-axis. (i) From this information, you can conclude that the x-component of the electric field in this region is (a) zero, (b) in the positive x-direction, or (c) in the negative x-direction. (ii) Suppose the electric potential is +2 V everywhere along the x-axis. From the same choices, what can you conclude about the x-component of the electric field now?
