Question
An aircraft with a wing-span of 40 m flies with a speed of 1080 km h−1 in the eastward direction at a constant altitude in the northern hemisphere, where the vertical component of earth's magnetic field is 1.75 ´ 10−5T. Then the emf that develops between the tips of the wings is
Answer: Option C
:
C
L=40 m, v=1080km h−1=300msec−1 and B=1.75×10−5T⇒
e=Blv=1.75×10−5×40×300=0.21V
