2. In the diagram to the right, point P lies on (a portion of) an equipo- tential curve. As shown, two friends drew what they thought the electric field at P would be. One drew E, as being tangent to, or parallel to, the curve as shown, while your other friend drew E2 and being at some other angle < 90 relative to this tangent line. In view of your answer to the question above, explain clearly why E cannot be a correct depiction of the electric field. P E2 3. Given your answer above, now explain why the electric field at point P couldn't even be 2, 4. Finally, with your answers to the previous questions, how must the electric field at this point (and thus any other point) be related to an equipotential curve? you about 5. Recall that it takes no work to move a charge through a conductor. What does this tell the relationship between conductors and equipotentials, and how electric field lines must intersect the surface of a charged conductor?
