In the mapping electric field experiment, the equipotential lines are obtained as shown in the diagram. The top plate is at 1.288 V and the bottom plate is at 0 V. The voltages of the equipotential lines are 1.197 V, 0.998 V, 0.823 V, 0.669 V, 0.463 V, 0.268 V, and 0.100 V as shown. The distance between any two adjacent equipotential lines is 0.9 cm.
A. Determine the magnitude of the electric field strength E for each adjacent pair of equipotential lines. (Your answer should have 6 values of the electric field strength)
B. Find the average value of E.
