Question : 60

Total: 80

A fighter plane of length 20m, wing span (distance from tip of one wing to the tip of the other wing) of 15m and height 5m is lying towards east over Delhi. Its speed is 240ms−1. The earth's magnetic field over Delhi is 5× 10−5T with the declination angle ∼0° and dip of θ such that sin‌θ=

. If the voltage developed is VB between the lower and upper side of the plane and VW between the tips of the wings then VB and VW are close to :

[Online April 10, 2016]

VB=40mV;VW=135 mV with left side of pilot at higher voltage
VB=45mV;VW=120 mV with right side of pilot at higher voltage
VB=40mV;VW=135 mV with right side of pilot at higher voltage
VB=45mV;VW=120 mV with left side of pilot at higher voltage
