Homework Help: Newton's law of gravitation

  1. Mar 29, 2010 #1
    An astronaut weighs 99.3 N on the surface of the moon. If the same astronaut orbits the moon at an altitude equal to the moons radius, what gravitational force (in N) does the moon exert on him at this altitude?

    can anybody get me going in the right direction? thanks
