An airplane with a wingspan of 60.0 m flies parallel to the Earth's surface at a point where the downward component of the Earth's magnetic field is 0.400 x l0^-4 T.If the induced potential between wingtips is 0.900 V,what is the plane's speed? A)250 m/s B)338 m/s C)375 m/s D)417 m/s

Question

Quizplus · Accepted Answer

The induced potential (emf) is given by the formula emf = B * v * L, where B is the magnetic field, v is the velocity, and L is the wingspan. Solving for v gives v = emf / (B * L) = 0.900 V / (0.400 x 10^-4 T * 60.0 m) = 375 m/s.
