Question

A train is moving with a
speed of 90kmph on a
meter gauge track, the
vertical component of
earth's magnetic field is
0.25x10*7. Induced emf
between the rails of the
track is​

Answer 1

Explanation:

The particle circulates under the influence of magnetic field. As the magnetic field is uniform, the charge comes out symmetrically. The angle subtended at the center is (180−2θ)
