A metal wire of mass 91 kilogram slides without friction on two horizontal rails spaced a distance of 73 meter apart. The track lies in a vertical uniform magnetic field of 65 T. A constant current 75 Amp from a generator flows down one rail, across the wire, down the other rail back to the generator.
Determine the velocity of the wire at t = 95 second, assuming it to be at rest at t =0.
Answer in units of m/s.
