11.7 Exercise 43

The density of charge carriers for copper is $8.47 \times 10^{28}$ electrons per cubic meter. What will be the Hall voltage reading from a probe made up of $3 \text{cm} \times \text{2 cm} \times \text{1 cm} \left(\text{L} \times \text{W} \times \text{T}\right)$ copper plate when a current of 1.5 A is passed through it in a magnetic field of 2.5 T perpendicular to the $3 \text{cm} \times \text{2 cm} .$
