Chapter 4: Q32E (page 984)
Consider the circuit shown in Fig., but with the bar moving to the right with speed v. As in Exercise 31, the bar has a length of 0.360 m, R= 45.0, and B= 0.650 T.
(a) Is the induced current in the circuit clockwise or counterclockwise?
(b) At an instant when the 45.0resistor is dissipating electrical energy at a rate of 0.840 J/s, what is the speed of the bar?
Short Answer
- The induced current in the circuit clockwise direction.
- At an instant when the 45.0 resistor is dissipating electrical energy at a rate of 0.840 J/s, the speed of the bar is 26.3 m/s.
