Which best describes the electromagnetic force? It is weaker than the gravitational force, with a greater range than the weak nuclear force. It is stronger than the gravitational force, with a greater range than the weak nuclear force. It is weaker than the strong nuclear force, with a smaller range than the weak nuclear force. It is stronger than the weak nuclear force, with a smaller range than the strong nuclear force.

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.
