A jet plane of wing span 20 m is travelling towards west at a speed of 400 m s^(-1). If the earth's total magnetic field is 4 xx 10^(-4) T and the dip angle is 30^(@), at that place, the voltage difference developed across the ends of the wing is |

Answer» Solution :Given, Speed (v) `= 400 ms^(-1)` MAGNETIC FIELD (B) `= 4xx10^(-4)T` Dip angle `theta = 30^(@)` We know that, Voltage difference = Blv sin `theta` `= 4xx10^(-4)xx20xx400xx sin 30^(@)` `= 32000xx10^(-4)xx sin 30` `= 32000xx10^(-4)xx(1)/(2)=1.6 V` |
