In mapping electric field experiment, the equipotential lines (dotted lines) between the two plates (labeled as 28.0 V and 0.0 V) are obtained as shown in the diagram. The distance between any two adjacent equipotential lines is 1.5 cm A. Determine the magnitude of the electric field strength E for each adjacent pair of equipotential lines including the plates (Your answer should have 7 values of the electric field strength) B. Find the average value of E. C. What is the magnitude of the force experienced by a charge +6C placed anywhere between the plates? 28.0 V 24.1 V 20.2 V 15.7 V 12.1 V 7.9 V 4.0 V 0.0 V
