A jet plane is travelling towards west at a speed of 1800 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth’s magnetic field at the location has a magnitude of `5 x× 10^(-4)` T and the dip angle is `30^@`.

Text Solution

Verified by Experts

Vertical component of B
`= 5.0 xx 10^(-4) sin 30^@`
`=2.5 xx 10^(-4)T`
`epsi = Blv`
`epsi = 2.5 xx 10^(-4) xx 25 xx 500`
`=3.125 V`
The emf induced is 3.1 V (using significant figures)
The direction of the wing is immaterial (as long as it is horizontal) for this answer.
