Speed and induced EMF of spacecraft orbiting a pulsar

[balling12]

Homework Statement

A spacecraft is in a circular orbit of radius 3.1 X 10^4 km around a 1.9 X 10^30 kg pulsar. The magnetic field of the pulsar at that radial distance is 1.4 X 10^2 T directed perpendicular to the velocity of the spacecraft . The spacecraft is 0.20 km long with a radius of 0.040 km and moves counterclockwise in the xy-plane around the pulsar
What is the speed of the spacecraft ?
Compute the induced emf.

Homework Equations

emf=Blv
