Draw equipotential lines near the positive and negative charges below with dashed lines. b) Draw solid electric field lines based on the fact that they are perpendicular to the equipotential lines at every point. Include arrows on the electric field lines to indicate their direction (since they represent vectors at each location).

Explanation:

A) The second figure depict electric field lines and equipotential lines for two equal but opposite charges. The equipotential lines can be drawn by making them perpendicular to the electric field lines. The potential is greatest (most positive) near the positive charge and least (most negative) near the negative charge.

B) The figure attached depicts an isolated point charge Q with its electric field lines in blue and equipotential lines in green. The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to electric field lines in every case.
