There are two parallel conducting guides, distant b 20 cm closed at one end by a resistor with R R = 4 N. Along the guides can slide without friction, under the action of the own weight, a mass con- B ductor bar m 10-2 kg. The device is immersed - in a uniform and constant magnetic field B = 1 T, orthogonal to the plane of the circuit. Calculate how speed, v(t), vary over time, the current i(t), the limit values v and i, the energy W1 dissi- pated in the circuit for each centimeter traveled by the bar when the limit values are reached.
