Simple pendulum.

  1. Jan 20, 2007 #1
    1. The problem statement, all variables and given/known data
    A simple pendulum is oscillating. When it is at the centre, what is the value of tension in string?

    2. Relevant equations
    The tension= The weight= mg


    3. The attempt at a solution

    Am i right? Please help!!

    No, you are NOT correct.
    At all times, the tension must provide the CENTRIPETAL ACCELERATION of the attached mass as well.

    oh yes. as well as the acceleration due to gravity. isnt it? now the force must be greater than mg.
