Question

Find the magnitude E of the electric field vector È for a point A between the V 2 volts and V 3 volts equipotential lines. Repeat for a point B between the V 3 volts and V- 4 volts equipotential lines. Repeat for a point C between the V 4 volts and V 5 volts equipotential lines. Repeat for a point D between the V 5 volts and V 6 volts equipotential lines. Points A through D should be approximately directly between the two electrodes. Indicate the direction of the electric field in each case. You must label on your sketch with the field lines and equipotentials the locations of the points where you are calculating the electric field. Since Eq. ES4-4 only holds true if the electric field is constant, you are making the simplifying assumption that the electric field is constant over this space. Although the field is not constant, this calculation gives you some idea of how the field changes as a function of position between the electrodes. c.

can you just use the formula to explain it (ie. use dA (as the distance between V2 and V3), etc.)
