As you travel through space, you find yourself moving into regions of ever-higher voltage. You are traveling . . .

A) perpendicularly to the electric field.
B) in exactly the same direction as the electric field.
C) in a region with no electric field.
D) in a direction exactly opposite to the electric field.

To determine the correct answer to this question, you need to understand how electric fields and electric potential work.

When traveling through regions of increasing voltage, it means you are moving towards regions with higher electric potential. To determine the direction of the electric field, we need to consider how positive charges move in an electric field.

Positive charges move from regions of higher potential to regions of lower potential. Therefore, when you find yourself moving into regions of higher voltage, it means you are moving against the electric field since you are moving from a region of lower potential to a region of higher potential.

So, the correct answer is D) in a direction exactly opposite to the electric field.
