Задача id10542

A jumper weighing 30 g begins to slide without friction along a U-shaped frame inclined at an angle of 30° to the horizon and placed in a uniform vertical magnetic field. The length of the jumper is 10 cm, its resistance is 1 mOhm, the field induction is 0.1 T. Find the steady speed of the jumper. Neglect the frame resistance, g = 10 m/s2.
