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 $240 ms^{−1}$. The earth’s magnetic field over Delhi is $5×10^{−5} T$ with the declination angle $~0^0$ and dip of $θ$ such that $\sin θ = \frac{2}{3}$. If the voltage developed is $V_B$ between the lower and upper side of the plane and $V_W$ between the tips of the wings then $V_B$ and $V_W$ are close to :
