Question

In Fig. $28-8$, show that the ratio of the Hall electric field magnitude $E$ to the magnitude $E_{C}$ of the electric field responsible for moving charge (the current) along the length of the strip is $$ \frac{E}{E_{C}}=\frac{B}{n e \rho} $$ where $\rho$ is the resistivity of the material and $n$ is the number density of the charge carriers. (b) Compute this ratio numerically for Problem 13. (See Table 26-1.)
