3. A zero-resistance rod of length 14.4 cm is being pushed along zero-resistance wires in a region where
a uniform magnetic field of strength 2.00 T is directed out of the page as shown. If the wires and rod
complete a circuit through a 2.90 N resistor then what velocity will the rod maintain if it is subjected to a
constant pushing force of 22.0 N?
Zero-resistance wires
Push
