(a) Express the magnitude of the electric field inside the strip in Figure 27.43 in terms of the width \(w\) of the strip and the potential difference \(V_{\mathrm{RL}}\).

(b) Given the magnitude \(B\) of the magnetic field, what is the speed at which the charge carriers travel?

(c) Show how this information, together with Eq. 27.16, can be used to determine the number density \(n\) of the charge carriers.
