A conducting rod of length l moves on two horizontal, frictionless rails, as shown in the attached file 'Figure P31.20'. If a constant force of 1.00 N moves the bar at 2.00 m/s through a magnetic field
B that is directed into the page,
(a) What is the current through the resistor R?
(b) What is the rate at which energy is delivered to the resistor?
(c) What is the mechanical power delivered by the force F_app?
Hello and thank you for posting your question to Brainmass!
The solution is attached below in two files. The solution in each is the same, only the file format is different. One in is MS-Word XP .doc format, while the other is in Acrobat .pdf format. You can choose the one that suits you the most.
Anyway, before you look at the solution let me suggest you try to solve the problem using ...
The solution provides a helpful guide in strategy to obtaining the answer as well as a detailed working-through attached in two different formats in case the former is not sufficient.
