Two satellites A and B move around earth in a circular orbit

  1. Dec 1, 2015 #1
    Two satellites A and B move around earth in a circular orbit. The mass of B is twice the mass of A then
    I agree that kinetic energy of B is greater than that of A. But what I couldn't understand was that why are speeds of A and B equal as given in the book.
    Shouldn't they differ according to the formula: orbital velocity =(GM/R)^1/2

    M is the mass of the Earth, not the satellite.
