Question

An aircraft with a wing-span of $40\ m$ files with a speed of $1080\ km\ h^{- 1}$ in the eastward direction at the constant altitude in the northern hemisphere, where the vertical component of earth’s magnetic field is $1.75 	imes 10^{- 5}T$. Then the emf that develops between the tips of the wings is

Dr. Abubacker · Accepted Answer

(c) $L = 40\ m,\ v = 1080km\ h^{- 1} = 300m\ s{ec}^{- 1}$ and $B = 1.75 	imes 10^{- 5}T \Rightarrow e = Blv = 1.75 	imes 10^{- 5} 	imes 40 	imes 300 = 0.21\ V$
