An aeroplane in which the distance between the tips of wings is `50 m` is flying horizontal with a speed of `360km//hr` over a place where the vertical components of earth magnetic field is `2.0xx10^(-4)webr//m^(2)`. The potential different between the tips of wings would be

Options

A. `0.1 V`
B. `1.0 V`
C. `0.2 V`
D. `0.01 V`

Answer

B

Explanation

`e=B_(v) v.l=2xx10^(-4)xx((360xx1000)/(3600))xx50`
`impliese=1V`
