Question
b. What is the relation/between the direction of the electric field and the electric field line at some point on the line? 2. UNIQUENESS OF EQUIPOTENTIAL AND FIELD LINES: a. Explain why two equipotential lines can not cross each other. Explain why two electric field lines in space can not cross. [Hint: What direction(s) would the field have at the intersection point?] b. Conductors provide shielding from electric fields. Discuss this aspect of Part B and C using your data. (Note: This experiment has limitations arising from the nature of the conductive paper and the contacts with the conductors.) 3.Explanation / Answer
2)
(a) Equipotential lines at different potentials can never cross either. This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.
(b) Electric field lines cannot cross. If they did, they would be telling you that the force on a charge at that location would point in two different directions, which does not make any sense at all.
