Description

A metal bridge with resistance R = 0.01 Ohm and length l = 0.5 m slides along a conductive frame without friction down at a constant speed of 8 m / s. The whole structure is in a uniform magnetic field with induction B = 0.01 T, directed perpendicularly frame plane. Considering the frame resistance equal to zero, determine the mass of the jumper.
