Textbook Question
Textbook QuestionTwo parallel resistanceless rails are 32 cm apart on a 6.0° ramp. They are joined at the bottom by a 0.60-Ω resistor. At the top a copper bar of mass 0.040 kg (ignore its resistance) is laid across the rails. Assuming a vertical 0.65-T magnetic field, what is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails?
