Joey drives along the “110 South” freeway and notices a mile marker that reads 260 miles. He drives until he reaches the 150 mile marker. He realizes that he went too far, so gets on the 110 North to the 175 mile marker. What is Joey’s displacement from the 260 mile marker?

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.
