The figure shows the equipotentials for each integer voltage between and including –4 V and +4 V for an arrangement of charges as shown. Assume that -4 V is the minimum potential and +4 V is the maximum for any point within the diagram. The table gives the closest distance from a point to a neighboring equipotential, either the one that is one volt lower or the one that is one volt higher.
1)What is the average electric field magnitude in V/cm at point b?
2)What is the average electric field magnitude in V/cm at point c?
3)What is the average electric field magnitude in V/cm at point d?
4)What is the average electric field magnitude in V/cm at point e?
5)What is the average electric field magnitude in V/cm at point f?
Explanation / Answer
E at b = 1/0.3(cm) = 333.33 N/C
E at c = 1/0.6(cm) = 166.66 N/C
E at d = 1/0.6(cm) = 166.66 N/C
E at e = 1/0.3(cm) = 333.33 N/C
E at f = 1/0.3(cm) = 333.33 N/C
