Angle theta of pundulum. help please

  1. Oct 20, 2008 #1
    1. The problem statement, all variables and given/known data

    Estimate the angle theta of the pendulum bob if it is 4.80km from the center of Mt. Everest.

    3. The attempt at a solution

    Tan(theta) = (GMeverest/r^2)/g

    I have been trying to use this formula, but i dont think its the right one?

    I think that formula should be ok for an estimate.
