The distance between the edges of the wings of an aeroplane is 30 metre. It is landing down with a velocity of 300 `km//hr`. If while landing, the wings of the aeroplane be east-west, find out the potentail difference between the edges of the wings. What will happen if the wings are along north south. Take `H = 0.4` gauss. |

Answer» When wings are along east-west, they intercept H. `:. E = B l upsilon = H l upsilon` `= (0.4 xx 10^(-4)) xx 30 xx (3 xx 10^(5))/(60 xx 60) = 0.1 V` However, when wings are along north-south, H. Intercept neither H nor V.So, in that case, induced e.m.f. = 0 |
