Concept #1: Equipotential Surfaces

Example #1: Field due to Equipotential Surfaces

Practice: Draw the electric field that corresponds to the equipotential surfaces shown in the following figure. Note that the potential is decreasing in the upward direction.

Additional Problems
Suppose a region of space has a uniform electric field, directed toward the right, as shown in the figure. Which statement is true? A) The voltage at all three location is the same. B) The voltage at point A and B are equal, and the voltage at point C is higher than the voltage at point A. C) The voltage at points A and B are equal, and the voltage at point C is lower than the voltage at point A. D) The voltage at point A is the highest, the voltage at point B is the second highest, and the voltage at point C is the lowest. E) None of the above.
In a region of space there is a uniform electric field with magnitude 800 N/C and that is in the +x-direction. If the electric potential at the origin is 300 V, what is the electric potential at a point that is on the -x-axis at x = -0.50 m?
Consider the figure below. Of the following elements, identify all that correspond to an equipotential line or surface. 1. line CD only 2. neither AB nor CD 3. line AB only 4. both AB and CD
For the equipotential lines shown in the diagram, the vector that best represents the direction of the electric field a point "P" is: A) Vector 1 B) Vector 2 C) Vector 3 D) Vector 4
A uniform electric field is directed along the +x-axis with  Ex = 200 V/m . If the electric potential at x = 0 m is +1000 V, what is the electric potential at  x = 2 m? [A] 600V [B] 1600V [C] -600V [D] -1600V [E] 0 V
P and Q are points within a uniform electric field that are separated by a distance of 0.2 m. The potential difference between P and Q is 75 V. Determine E 15 V/m 75 V/m 375 V/m 750 V/m 1100 V/m
Two spherical charged conductors placed 6 cm apart produce the equipotential surfaces shown in the figure. The change in potential between each surface is constant, with the 0V line being equidistant from the two charges, and some +V0 at the left-most surface.What is the best comparison of the electric fields at points A and F?A. Both point to the leftB. Both point to the rightC. Field at A points to the right and field at F points to the leftD. Field at A points to the left and field at F points to the rightE. Cannot know without knowing nature of the charges
