Question:

Repeat Problem 88 if the plane flies 30.0° west of south at 180 m/s instead.
Repeat Problem
An airplane is flying due north at 180 m/s. Earth's magnetic field has a northward component of 0.30 mT and an upward component of 0.38 mT.
(a) If the wingspan (distance between the wingtips) is 46 m, what is the motional emf between the wingtips?
(b) Which wingtip is positively charged?
