Time period

  1. Dec 29, 2011 #1
    In the center of earth, g=0,

    T=2*3.14*√(L/g) =∞

    question: what do you mean by the "infinite time period"? and explain the situation of simple pendulum at the center of earth

    in your equation you're dividing by g, and if g = 0 then its infinite or undefined... basically if there is no gravity, the pendulum will not oscillate. It will just float there, hence infinite period

    If there is no gravitational force to pull the pendulum down how long will it take to swing?
