Problem

A flat conducting plate of width

0.010\,\text{m}

carries electrons that drift at an average speed of

2.0\times10^{-2}\,\text{m}\!\cdot\!\text{s}^{-1}

while a

0.50\,\text{T}

magnetic field is directed perpendicular to the plate. What is the magnitude of the Hall voltage that develops across the width of the plate? (a)

1.0\times10^{-2}\,\text{V}

(b)

1.0\times10^{-4}\,\text{V}

(c)

5.0\times10^{-3}\,\text{V}

(d)

1.0\times10^{-6}\,\text{V}
