Question:

Let Fig. represent a strip of an unknown metal of the same dimensions as those of the silver ribbon in Exercise 27.51. When the magnetic field is 2.29 T and the current is 78.0 A, the Hall emf is found to be 131 µV. What does the simplified model of the Hall effect presented in Section 27.9 give for the density of free electrons in the unknown metal?
