Question

An aeroplane is flying horizontally from west to east with a velocity of 900 km/hour. Calculate the potential difference developed between the ends of its wings having a span of 20 m. The horizontal component of the earth's magnetic field is 5 104 t and the angle of dip is 30.

Answer 1

I think this question is from CBSE 2018 physics Paper.

Potential developed= BVL sin30

V=900km/hr = 250m/s

B= 5×10^(-4) Tesla

L= 30m

Put the value and get the answer.
