A Airplane Having a Metal Surface and a Wingspan of 25.0

question 73

Short Answer

A airplane having a metal surface and a wingspan of 25.0 m flies horizontally at 200 m/s where the earth's $\vec { B }$ field is vertical with magnitude 45.0 μT.
(a)What emf is induced across the wings?
(b)What wingspan would the plane need to produce 1.00-V emf across its wings?
(c)The plane now reverses direction.Does the polarity of the wingtip emf change? That is,if the left wing was positive before,does it now become negative?
