Question

An aeroplane, with its wings spread 10 m, is flying at a speed of 180 km/h in a horizontal direction. The total intensity of earth's field at that part is 2.5 104 Wb/m2 and the angle of dip is 60. The emf induced between the tips of the plane wings will be __________.

Correct answer
D108.25 mV

Step-by-step explanation

ind = (Bv) LV and Bv = BTotal sin60o

ind = (2.5 104)(sin 60o) 10 180

= 108.25 mV
