JOV 4. For Step P6, Part (a), compute the amount of work involved in transferring a charge of 2C: (a) from the negative electrode to the positive electrode; . used in (b) from the negative electrode to the positive electrode along a 45° angle; experiment. (e) from the negative electrode to the positive electrode, and then back to the first one; (d) along an equipotential line. (Hint: There are different ways to calculate the work; if you use the right method, it greatly simplifies the problem.) Use the voltage value you used in the experiment. Show your calculations and justify your answers. Would you obtain the same results or different results if you were to use different types of electrodes? Justify your answer.

6. Based on the electric field between parallel-plate electrodes and the value of the potential difference measured in Step P6, Part (a), does the voltage increase linearly, quadratically, or like 1/x2 between the plates, where x is the distance from one of the plates? Discuss the measured value at the mid-point between the two plates and state what it indicates. What does Eq. 11.2 indicate?
