Question

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^(o) and dip of θ such that sin θ = 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:

Accepted Answer

(B) V B = 45 m V; V W = 120 m V with left side of pilot at higher voltage

Answer

(A) V B = 45 m V; V W = 120 m V with right side of pilot at higher voltage

Answer

(C) V B = 40 m V; V W = 135 m V with right side of pilot at high voltage

Answer

(D) V B = 40 m V; V W = 135 m V with left side of pilot at higher voltage
