A conductor  rod `AB` of mass `m` slides  without friction over two  long conducting  rails  separated by a distance (Fig) At the  left end the raidls are interconnected by a resistance `R`. The  system  is located  in a unifrom  magnetic  fileld perpendicular  to the  plane of the loop. At the moment  `t = 0` the rod  `AB` starts moving to  the right  with an initial  velocity `v_(0)`. Neglecting  the resistances of the  rails  and the rod `AB`, as wellas the self -indcuctance, find: (a) the distance  covered  by the rod  until  it comes  to  a  standsill,  (b) the amount  of heat  generated  in the resitance `R` during  this  process.
