A dipole consisting of charges +Q and −Q , with Q=29 nC, is fixed at the vertices of an equilateral triangle with sides of length 1.00 cm . The work required to move a particle with a charge q from the other vertex to the center of the line joining the fixed charges is

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.
