A fighter plane of length $\displaystyle 20$ m, wing span (distance from tip of one wing to the tip of the other wing) of $\displaystyle 15$ m and height $\displaystyle 5$ m is flying towards east over Delhi. Its speed is $\displaystyle 240 \mathrm{~ms}^{-1}$. The earth's magnetic field over Delhi is $\displaystyle 5 \times 10^{-5} \mathrm{~T}$ with the declination angle ~$\displaystyle 0$° and dip of $\displaystyle \theta$ such that $\displaystyle \sin \theta=\frac{2}{3}$. If the voltage developed is $\displaystyle V_B$ between the lower and upper side of the plane and $\displaystyle V_W$ between the tips of the wings then $\displaystyle V_B$ and $\displaystyle V_W$ are close to :
