A straight conductor 1 meter long moves a right angles to both, its length and a uniform magnetic field. If the speed of the conductor is 2.0 ms^(-1) and the strength of the magnetic field is 10^(4) gauss, find the value of induced emf in volt.

Two trains A and B of length 400 m each are moving on two parallel tracks with a uniform speed of 72 km h^-1 in the same direction, with A ahead of B. The driver of B decides to overtake A and accelerates by 1 m s^-2 . If after 50 s, the guard of B just brushes past the driver of A, what was the original distance between them ?

Two trains A and B are moving on parallel tracks with same speed and in the same direction. An observer P is sitting in train A and another person Q is sitting in train B. Is Q at rest with respect to P?
