## Homework Statement

A conducting rail in contact with conducting wires, oriented perpendicular to both wires, is pushed with constant speed, causing an induced current of 0.69 A. B = 0.50 T and R (Resistor) = 2.0

Calculate the "push" force necessary to maintain the rail's constant speed.

## Homework Equations

I assume I use F = q * v * b

## The Attempt at a Solution

I don't think I am using the correct equation here because there is no charge on the conducting rail. I am thinking I need to use an equation that I am not yet familiar with. I went to the chapter in my book over induction and I can't find any equations dealing with a 'push' force.
