An aeroplane, in which the distance between the tips of wings is 50 m, is flying with a speed of 360 km h^(-1) over a place where the vertical component of earth's magnetic field is 2.0 xx 10^(-4)T. The potential difference between the tips of wings would be

Answer»

0.1V
1.0V
0.2 V
0.01 V

Solution :`V=Blv and v=360"km H"^(-1)=100MS^(-1)`
`V=(2.0 xx 10^(-4)) xx 50 xx 100=1.0V`
