An airplane 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. 0.01 V
C. 0.2 V
D. 1.0 V

Answer

D

Explanation

As, potential difference,
`V=Bvl=(2.0xx10^(-4))(360xx(5)/(18))(50)=1.0V`
