Need Help in Solving Physics Question...?

Question

In 1996, NASA performed an experiment called the Tethered Satellite experiment. In this experiment a 2.20 104 m length of wire was let out by the space shuttle Atlantis to generate a motional emf. The shuttle had an orbital speed of 7.70 103 m/s, and the magnitude of the earth's magnetic field at the location of the wire was 4.90 10-5 T. If the wire had moved perpendicular to the earth's magnetic field, what would have been the motional emf generated between the ends of the wire?
