(A) The motional electromotive force $(e)$ induced across a conductor of length $(l)$ moving with velocity $(v)$ in a magnetic field $(B)$ is given by the formula: $e = Bvl$.Given:Length of wing span $(l)$ = $20 \, m$.Vertical component of Earth's magnetic field $(B)$ = $5 	imes 10^{-5} \, T$.Velocity of the aeroplane $(v)$ = $360 \, km/h$.First,convert the velocity into $SI$ units $(m/s)$:$v = 360 	imes \frac{5}{18} = 100 \, m/s$.Now,substitute the values into the formula:$e = (5 	imes 10^{-5} \, T) 	imes (100 \, m/s) 	imes (20 \, m)$.$e = 5 	imes 10^{-5} 	imes 2000 = 5 	imes 10^{-5} 	imes 2 	imes 10^3 = 10 	imes 10^{-2} = 0.1 \, V$.Therefore,the potential difference produced is $0.1 \, V$.

The wing span of an aeroplane is $20$ $m$. It is flying in a field where the vertical component of the Earth's magnetic field is $5 \times 10^{-5} \, T$,with a velocity of $360 \, km/h$. The potential difference produced between the wing tips will be ....... $V$.
