I am doing a question about Current balances & Electromagnet Induction and i cnat seem to figure out a few thing and i was hoping someone could help me, so here is the question:(adsbygoogle = window.adsbygoogle || []).push({});

A conducting bar moves to the right along parallel,frictionless conducting rails connected on one end by a 6.00ohm resistor. A 2.50T magnetic field is directed into the paper. The length is 1.20m and the mass of the bar is negligible.

*calculate teh applied force that is necessary to move the bar to the right at a constant speed of 2.00m/s.

*determine the rate at which energy dissipated in the resistor.

*calculate the power outputted by the resistor if the speed of the rod is doubled.
