An aeroplane in which the distance between the tips of the wings in $50 m$ is flying horizontally with a speed of $360 k m h^{- 1}$ over a place where the vertical component of Earth's magnetic field is $2 \times 10^{- 4}$ $W b m^{- 2}$ . The potential difference between the tips of the wings would be

Options:

Answer:

Solution:

Here, $l = 50 m, v = 360 k m h^{- 1} = 100 m s^{- 1}$

$B = 2 \times 10^{- 4} W b m^{- 2}$

Potential difference $e = B l v = 2 \times 10^{- 4} \times 50 \times 100 = 1 V$
