An aeroplane is moving towards north horizontally with a speed of 200m/s at a place where the vertical component of earths magnetic field is 0.5×10−4 tesla. Then the induced e.m.f. set up between the tips of the wings of the plane if they are 10m apart is:
An airplane in which the distance between the tips of the wings is 50 meter is flying horizontally with a speed of 360 km/hour over a place where the vertical component of earths magnetic field is 2.0×10−4Testa. The potential difference between the tips of the wings would be:-
