Hall Voltage Calculation

Question

A rectangular copper strip carries a current $$I = 15~\mathrm{A}$$ in the positive x-direction. The strip, which has a width of $$w = 2.0~\mathrm{cm}$$ in the y-direction, is placed in a uniform magnetic field $$B = 0.25~\mathrm{T}$$ pointing in the positive z-direction. Determine the magnitude of the Hall voltage across the width of the strip. (The charge carrier density for copper is $$n = 8.5 	imes 10^{28}~	ext{electrons}/\mathrm{m}^3$$, and the elementary charge is $$e = 1.6 	imes 10^{-19}~\mathrm{C}$$.)
