A jet plane is travelling due west at the speed of 1800 km/h. what is the voltage difference developed between the ends of the wings 25m long, if the earths magnetic field at the location is 0.0005 T and the dip angle is 30°?

Expert Answer:

Velocity of jet plane = 1800 km/h
v= 1800 × 5/18 m/s = 500 m/s
 
Length between the wings (l)= 25 m
Magnetic field (B)= 0.0005 T
Angle of dip (d) = 30°
 
Voltage difference between the two ends of wings called e.m.f (e) =Bv × v × l
Bv - vertical componnet of magnetic field
Bv = B (sin d) =0.0005 × sin 30° = 0.00025
 
e= 0.00025 × 500 × 25 
 
e= 3.125 V
