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)`A. Will be converted fully into heat energy in the resistorB. Will enable rod to continue to move with velocity `v_(0)` since the rails are frictionlessC. Will be converted fully into magnetic energy due to induced currentD. Will be converted into the work done against the magnetic field |
