A circular railway track of radius r is banked at angle theta so that a train moving with speed v can safely go round the track. A student writes: tan theta =rg//v^(2) . Why this relation is not correct? (i) Equality of dimensions does not guarantee correctness of the relation . (ii) Dimensionally correct relation may not be numerically correct. iii) The relation is dimensionally incorrect.

The two rails, separated by 1m, of a railway track are connected to a voltmeter. What will be the reading of the voltmeter when a train travels on the rails with speed 5m/s. The earth's magnetic field at the place is 4xx10^(-4)T , and the angle of dip is 30^(º) .

Two rails of a railway track, insulated from each other and the ground, are connected to a millivoltmetre. What is the reading of the millivoltmetre when a train travels at a speed of 20 ms^(-1) along the track? Given that the vertical component of earth's magnetic field is 0.2xx10^(-4)"Wbm"^(-2) and the rails are separated by 1 m

Two parallel rails of a railway track insulated from each other and with the ground are connected to a millivoltmeter. The distance between the rails is one metre. A train is traveling with a velocity of 72 km ph along the track. The reading of the millivoltmetre (in m V ) is : (Vertical component of the earth's magnetic induction is 2 xx 10^(-5) T )
