Question

An aeroplane is flying horizontally from west to east part of velocity of 900 km per hour calculate the potential difference developed in the ends of a switch

Answer 1

pls mark on the brain list pls

Potential difference developed between the ends of the wings 'e' = BlvsinФ

v= 900 km/hr =250 m/s

b=5* 10^{-4} T

l=20m

Ф= 30°

∴ e = 5*1010^{-4} * 20 * 250 * sin 30°

= 1.25
