Ajet plane is travelling towards west at a of 1800 km h^(-1). What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth's magnetic field at the location has a magnitude of 5.0 xx 10^(-4) and the dip angle is 30^(@). |

Answer» Solution :Velocity of plane, `v = 1800 km h^(-1)= 500 ms^(-1)` Vertical COMPONENT of Earth.s magnetic field B is `B_(V) = B SIN delta = 5.0 xx 10^(-4) sin 30^(@) (delta "is the angle of DIP")` `= 2.5 xx 10^(-4)T` , Wing span, L = 25 m Induced emf across the wind span will be `epsilon = B_(V)lv =25 xx 10^(-4) xx 25 xx 500= 3.125 V` |
