Vedclass · Answer

(A) Given: Wing span $l = 20 \,m$, speed of jet plane $v = 400 \,ms^{-1}$, Earth's total magnetic field $B = 4 	imes 10^{-4} \,T$, and angle of dip $	heta = 30^{\circ}$.The motional electromotive force (emf) induced across the wings is given by $e = B_v l v$, where $B_v$ is the vertical component of the Earth's magnetic field.The vertical component $B_v$ is calculated as:$B_v = B \sin 	heta = 4 	imes 10^{-4} 	imes \sin 30^{\circ} = 4 	imes 10^{-4} 	imes 0.5 = 2 	imes 10^{-4} \,T$.Now, substituting the values into the emf formula:$e = (2 	imes 10^{-4} \,T) 	imes (20 \,m) 	imes (400 \,ms^{-1})$$e = 16000 	imes 10^{-4} \,V = 1.6 \,V$.Thus, the voltage difference developed across the ends of the wing is $1.6 \,V$.

$A$ jet plane of wing span $20 \,m$ is travelling towards west at a speed of $400 \,ms^{-1}$. If the earth's total magnetic field is $4 \times 10^{-4} \,T$ and the dip angle is $30^{\circ}$ at that place, the voltage difference developed across the ends of the wing is (in $\,V$)
