A uniform electric field has magnitude E and is directed in the negative x direction. The potential difference between point a (at x= 0.50 m ) and point b (at x= 0.85 m ) is 300 V . Part A Which point, a or b, is at the higher potential?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
