Question
Two rails of a railway track insulated from each other and the ground are connected to a milli voltmeter. What is the reading of voltmeter, when a train travels with a speed of 180 km/hr along the track. Given that the vertical component of earth's magnetic field is 0.2× 10−4 T and the rails are separated by 1 metre

Solution
The correct option is C 10−3 Volt
e=Bv.vl=0.2× 10−4× (180× 10003600)× 1=10−3V
e=Bv.vl=0.2× 10−4× (180× 10003600)× 1=10−3V
