Question

A jet plane having a wing-span of 25 m is travelling horizontally towards East with a speed of 3600 k m / h r . If the Earth's magnetic field at the location is 4 × 10 - 4 T and the angle of dip is 30 o , then the potential difference between the ends of the wing is

TestHub · Accepted Answer

Given, B = 4 × 10 - 4 T , l = 25 m , v = 3600 k m / h = 1000 m / s, θ = 30 o E = B l v sin ⁡ θ = 4 × 10 − 4 × 25 × 1000 × sin 30 ° = 5 V
