A helicopter rises vertically upwards with a speed of 100 `m//s`. If the helicopter has a length of 10m and horizontal component of earth's magnetic field is `5 xx 10^(-3)Wb//m^(2)`, then the induced emf between the tip of the nose and the tail of the helicopter is

A helicopter rise verticaly with a speed of 10ms^(-1) . If helicopter has a length of 10 m and the horizontal component of the earth's magentic field is 1.5 xx 10^(-3) Wbm^(2) , the emf induced between the tip of the nose and the tail of the helicopter, is

A helicopter is moving in upward direction with speed of 10 m/s. If the length of the helicopter is 10 m and the horizontal component of magnetic field of earth is 1.5 xx 10^(-3) "Wb"/ m^2 then the induced emf produced across the foremost (nose) and end part (tail) of the helicopter will be ____

A metre gauge train is running towards north with a speed of 20 m//s . If the vertical component of earth's magnetic induction is 3 xx 10^(-4) Wb//m^(2) , then the e.m.f. induced at the end of the axle is
