Shows a rod of length l and resistance r moving on two rails shorted by a resistance R . A uniform magnetic field B is present normal to the plane of rod and rails. Show the electrical equivalence of each branch.

A vertical ring of radius r and resistance on R falls vertically. It is in contact with two vertical rails which are joined at the top. The rails are without friction and resistance. There is a horizontal uniform, magnetic field of magnitude B perpendicular to the plane of the ring and the rails. When the speed of the ring is v , the current in the section PQ is

On a railway curve, the outside rail is laid higher than the inside one so that resultant force exerted on the wheels of the rail car by the tops of the rails will

The metro which has been recently inroduced in Mumbai, encounters a sharp turn between Andheri and Chakala. To avoid any derailing issues, the authorities thought of banking the rails.The turn is of a radius of 400 m and the maximum speed attained by Mumbai Metro is 72 km//hr . IF the distance between the rails is 1 m then through what height should the outer rail be raised?

Two identical trains are moving on rails along the equator on earth in opposite directions with the same speed. The pressure exerted on rails will be:
