Two parallel fixed conducting rails are `l` distance apart. They are connected by a conducting wire xy. A uniform magnetic field B is applied normal to its plane. Two other rods PQ and RT(RS = ST) are moved with a constant velocity v. Resistance/ length of these two rods are `lamda` no other wire has resistance. Then :

Shows a wire sliding on two parallel, conducting rails placed at a separation l. A magnetic feld B exists in a direction perpendicular to the plane of the rails. What force is necessary to keep the wire moving at a constant velocity v ?

PQ and MN are two parallel conductors at a distance l apart and connected by a resistance R as shown in figure. They are placed in a magnetic field B which is perpendicular to the plane of the conductors. A wire XY is placed over PQ and MN and then made to slide over PQ and MN with a velocity v. Neglecting the resistance of PQ, MN and wire XY, calculate the work done per second to slide the wire XY.

A conducting rod MN of mass m and length 'l' is placed on parallel smooth conducting rails connected to an uncharged capacitor of capacitance C and a battery of emf epsilon as shown.
