Question

C Exercise 20.12 A metal airplane with a wingspan of 39m flies horizontally along a north-south route in the northern hemisphere at a constant speed of 330km/h in a region where the vertical component of the Earth?s magnetic field is 7.0x10^-5T. Part A What is the magnitude of the induced emf between the tips of its wings? Express your answer using two significant figures. Epsilon = _______________ V Part B If the easternmost wing tip is negatively charged, is the plane flying due north or due south? due north due south

Explanation / Answer

apply induced emf e = LVB

e = 39 * (330*5/18) * 7e5

e = 0.250 Volts
