An aircraft with a wingspan of 40 m flies with a speed of 1080 km/hr in the eastward direction at a constant altitude in the northern hemisphere, where the vertical component of the earth's magnetic field `1.75 xx10^(-5)` . Then the emf developed between the tips of the wings is

A

2.1V

B

0.21V

C

0.34V

D

0.5V

Text Solution

Verified by Experts

The correct Answer is:
B

`epsi= B_(v) lv= 1.75 xx 10^(-5) xx 40 xx 1080 xx (5)/(18)= 21000 xx 10^(-5)= 0.21V`
