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.

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.
