Circuit with Resistance#

Shown below is a conducting rod that slides along metal rails. The apparatus is in a uniform magnetic field of strength \({{params.B }} \textrm{ T}\), which is directly into the page. The rod is pulled to the right at a constant speed of \({{params.v }} \textrm{ m/s}\) by a force \(\overrightarrow{F}\). The only significant resistance in the circuit comes from the \(2.0 \rm\ \Omega\) resistor shown.
