A uniform electric field is directed parallel to the +y axis. If a positive test charge begins at the origin and moves upward along the y axis, how does the electric potential vary, if at all?
1. The electric potential will decrease with increasing y.
2. The electric potential will increase with increasing y.
3. The electric potential will remain constant with increasing y.
4. Too little information is given to answer this question.
