Answer on Question #81070, Physics / Electromagnetism

Question:

A Plane travelling towards west at speed of $1800\mathrm{km/hour}$ what is the voltage difference developed between the ends of wings having a span of 25 meter, if the earth magnetic field at the location has a magnitude of $5\times 10^{\wedge}2\mathrm{T}$ and the dip angle is $30{}^{\circ}$

Solution:

The voltage difference $U = El = vB_{v}l = v \cdot B \cdot \cos 30 \cdot l = \frac{1800 \cdot 5 \cdot 10^{-5} \cdot 0.87 \cdot 25}{3.6} = 0.54 \, \text{V}$,

The answer:

The voltage difference $U = El = vB_{v}l = v \cdot B \cdot \cos 30 \cdot l = \frac{1800 \cdot 5 \cdot 10^{-5} \cdot 0.87 \cdot 25}{3.6} = 0.54 \, \text{V}$, because the correct magnetic field induction has a magnitude of $5 \times 10^{\wedge} - 5 \, \text{T}$
