In the Electric Field Mapping experiment, suppose you used two electrodes separated by a distance L and a power supply with emf Vo. Then you measure V for points along a straight line perpendicular to the electrodes, joining the centers of the positive and negative electrodes. You connect the negative terminal of the voltmeter to the cathode and the positive terminal to the pointer placed at a point in the tray along the line joining the two electrodes, a distance d from the cathode. Which of the following is true? O a. During the experiment we vary d but keep Vo fixed. O b. The slope of V vs. d is negative. O c. There is a linear relation between d and L. O d. The slope of V vs. d is positive and depends on Vo only. Oe. The positive terminal of the voltmeter should be connected to the cathode and the negative terminal to the point between the two electrodes.

Question
Transcribed Image Text:In the Electric Field Mapping experiment, suppose you used two electrodes separated by a distance L and a
power supply with emf Vo. Then you measure V for points along a straight line perpendicular to the electrodes,
joining the centers of the positive and negative electrodes. You connect the negative terminal of the voltmeter
to the cathode and the positive terminal to the pointer placed at a point in the tray along the line joining the
two electrodes, a distance d from the cathode. Which of the following is true?
O a. During the experiment we vary d but keep Vo fixed.
Ob. The slope of V vs. d is negative.
O c. There is a linear relation between d and L.
O d. The slope of V vs. d is positive and depends on Vo only.
O e. The positive terminal of the voltmeter should be connected to the cathode and the negative terminal to
the point between the two electrodes.
