1. The problem statement, all variables and given/known data 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. 2. Relevant equations emf=Blv 3. The attempt at a solution Not sure which information I need to use from the problem in order to determine the velocity?
