Solving a problem in physics section 46 paragraph 5 el

5. Two smooth closed metal tires, the distance between them is 30 cm, with a sliding bridge that can move without friction, it is in a uniform magnetic field with induction B = 0.1 T, perpendicular to the plane of the loop. Jumper mass m = 5 g glides down at a constant velocity υ = 0,5 m / s. Determine the resistance bridge, ignoring the self-induction loop resistance and the rest of the circuit.
