A jet plane is travelling west at `450 ms^(-1)`. If the horizontal component of Earth's magnetic field at that place is `4xx10^(-4)` T and the angle of dip is `30^(@)`, find the emf induced between the ends of wings having a span of `30` m.

Explanation

`3.12` V, use `e=B_(V)//v`
where, `B_(V)=B_(H)tan delta`
