Multiple Choice

FIGURE 27-7
-A Hall effect experiment is set-up with a conducting strip placed inside a magnetic field. A voltmeter is used to measure the voltage in the direction perpendicular to the direction of the current through the strip, as shown in Fig. 27-7. A current I runs in the positive y-direction, while the magnetic field is oriented in the positive z-direction. If the reading of the voltmeter is positive when the wires are connected to its terminals as shown below, what is the sign of the charge carriers in this strip?

• A)negative
• B)negative on the edges and positive in the middle of the strip
• C)could be either one
• D)positive on the edges and negative in the middle of the strip
• E)positive
