A fighter plane of length 20 m, wing span (distance from tip of one wing to the tip of the other wing) of 15 m and height 5 m is flying towards east over Delhi. Its speed is 240ms^{-1}.The earth's magnetic field over Delhi is 5\times10^{-5}T with the declination angle ∼0^\circ and dip of θ such that \text{\sin}\theta=2/3.If the voltage developed is V_B between the lower and upper side of the plane and VW between the tips of the wings then V_B and V_W are close to : [Main 10 Apr 2016]

Correct Answer is : VB=45mV;VW=120mV with left side of pilot at higher voltage

V_B=45mV;V_W=120mV with right side of pilot at higher voltage

V_B=45mV;V_W=120mV with left side of pilot at higher voltage

V_B=40mV;V_W=135mV with right side of pilot at high voltage

V_B=40mV;V_W=135mV with left side of pilot at higher voltage

A fighter plane of length 20 m, wing span (distance from tip of one wing to the tip of the other wing) of 15 m and height 5 m is flying 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 :
