$A$ 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 $5 \times 10^{-5}\,T$ with the declination angle $\, 0^\circ$ and dip of $\theta$ such that $\sin \theta = 2/3$. 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:

  • A
    $V_B = 40\, mV$; $V_W = 135\,mV$ with left side of pilot at higher voltage
  • B
    $V_B = 45\,mV$; $V_W = 120\, mV$ with right side of pilot at higher voltage
  • C
    $V_B= 40\, mV$; $V_W = 135\,mV$ with right side of pilot at higher voltage
  • D
    $V_B = 45\, mV$; $V_W = 120\, mV$ with left side of pilot at higher voltage
