A conducting rod of mass m and length l is free to move without friction on two parallel long conducting rails, as shown below. There is a resistance R across the rails. In the entire space around, there is a uniform magnetic field B normal to the plane of the rod and rails. The rod is given an impulsive velocity v_(0) - Finally, the initial energy (1)/(2) mv_(0)^(2)

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 :
