A Hall Voltage Is Measured Across the Width of Two

Multiple Choice

A Hall voltage is measured across the width of two rods under the same experimental conditions. The only variation is that the thickness of the second rod is twice that of the first rod. The Hall voltage across the second rod will be

A) twice the value measured across the first rod.
B) half of the value measured across the first rod.
C) one-quarter the value measured across the first rod.
D) Hold on; the value of the voltage will not change.
