Magnetic Field

  1. Oct 7, 2009 #1
    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?

    What is the centripetal on the satellite?
    What is the gravitational force on the satellite?
