A fighter plane of length 20m20\,\text{m}, wing span 15m15\,\text{m} and height 5m5\,\text{m} is flying towards east over Delhi. Its speed is 240ms1240\,\text{m\,s}^{-1}. The earth's magnetic field over Delhi is 5×105T5 \times 10^{-5}\,\text{T} with the declination angle 00^\circ and dip δ\delta such that sinδ=1/3\sin\delta = 1/\sqrt{3}. If the voltage developed is VBV_B between the lower and upper side of the plane and VWV_W between the tips of the wings then VBV_B and VWV_W are close to :
