A jet plane having a wing-span of 
is travelling horizontally towards east with a speed of 
. If the Earth's magnetic field at the location is 
and the angle of dip is 
, then the potential difference between the ends of the wing is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Here, wing-span, 
Speed of the plane, 
Earth's magnetic field, 
Angle of dip, 
As the plane is moving horizontally toward east, it will cut the vertical component of the Earth's magnetic field which is given by
The potential difference (i.e., induced emf) developed between the ends of the wing is
