Question
Determine the potential difference developed across the wings of a Boeing 747 airliner when traveling north at $240 \mathrm{m} / \mathrm{s}$.The wingspan is $60 \mathrm{m}$.Earth’s $5.0 \times 10^{5}\mathrm{T}$ magnetic field points in a direction $60^{\circ}$ below a horizontal line directed north. In solving this problem, follow the outline developed in the previous problem. Note that the magnetic field is not perpendicular to the plane’s velocity.
Solution
VerifiedStep 1
1 of 5
Firstly, sketch and explain the system.

Secondly, derive the expression for the electric force $F_{\overrightarrow{E}}$ and the magnetic force $F_{\overrightarrow{B}}$ which are balanced.

Finally, substitute and determine the potential difference developed across the wings of a Boeing 747 airliner while traveling.
