Two metal strips of length l each are placed parallel to each other in contact with an electric circuit as shown in Fig. 1.135. The entire structure is placed on a smooth horizontal floor in a region in which magnetic field is existing in vertical direction.

The distance travelled by the wire as a function of time is best given by

Two metal strips, each of length, each of length l, are clamped parallel to each other on a horizontal floor with a separation b between them. A wire of mass m line on them perpendicularly as shown in figure. A vertically upward magnetic field of strenght B exists in the space. The matal strips are smooth but the cofficient of freiction between the wire and the floor is mu . A current i is established when the switch S is closed at the instant t=0 . Discuss the motion of the wire after the switch is closed. How far away from the strips will the wire reach?

The current generator i_g , shown in , sends a constant current I through the circuit. The wire ab has a length l and mass m and can slide on the smooth, horizontal rails connected to l_g . The entire system lies in a vertical magnetic field B. Find velocity of the wire as a function of time.

A wire ab of length l, mass m and resistance R slides on a smooth thick pair of metallic rails joined at the bottom as shown in fig. The plane of the rails makes an angle theta with the horizontal. A vertical magnetic field B exist in the region. If the wire slides on the rails at a constant speed v, then the value of B is -

A conducting wire of length l and mass m is placed on two inclined rails as shown in figure. A current I is flowig in the wire in the direction shown When no magnetic field is present in the region, the wire is just on the verge of sliding. When a vertically upward magnetic field is switched on, the wire starts moving up the incline. The distance travelled by the wire as a function of time t will be

A thin uniform rod of mass M and length L is lying on a smooth horizontal floor. It is struck by a force F normally at one end. The contact lasts for a very small time t_(0) . Find the distance traveled by the rod in the time in which it is turned by pi//2 .
