Question

Aircraft sometimes acquire small static charges. Suppose a supersonic jet has a 0.60 µC charge and flies 30ᵒ north of west at a speed of 660 m s-1 over the Earth’s south magnetic pole, where the 8.00 X 10-5 T magnetic field points straight up. Determine the magnetic force on the supersonic jet.

Answer 1

Magnetic force

$F=qvBsin\theta$

$$F=0.60\times10^{-6}\times660\times8\times10^{-5}sin30°=1.584\times10^{-8}N$$
