22.6 Exercise 5

Avg difficulty 2.5

(a) What is the speed of a supersonic aircraft with a 17.0-m wingspan, if it experiences a 1.60-V Hall voltage between its wing tips when in level flight over the north magnetic pole, where the Earth’s field strength is 8.00×10−5T?8 . \text{00} \times \text{10}^{- 5} \text{T}? (b) Explain why very little current flows as a result of this Hall voltage.
