Two trains A and B of length 400 m each are moving on two parallel tracks with a uniform speed of 72 km/ h 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 50s, the guard of B just brushes past the driver of A, what was the original distance between them ?

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 stations A and B are 2km apart. A train moves at first with a uniform acceleration a_(1) and then with a uniform retardation a_(2) to travel the distance AB in 4 min.Then

Two electrons are moving towards each other with a velocity of 10^6m/s . What will be the closest distance of approach between them?

A train begins its journey from a station with a uniform acceleration of 0.2 "m.s"^(-2) and moves for 1 min. Next, it moves for a further 5 min at uniform velocity. It then appIies brakes producing a retardation of 0.3 "m.s"^(-2) and stops at the next station. What is the distance between the two station?

A straight conductor of length 50 cm is moving with a velocity 5 m. s^(-1) in a magnetic field of strength 2T in a direction perpendicular to the field. What is the emf (in V) induced between the two ends of the conductor?
