Melting bob of pendulum

  1. Mar 22, 2008 #1
    1. The problem statement, all variables and given/known data

    the bob of an oscillating pendulum is made of ice.how is the time period affected if the bob starts melting?

    2. Relevant equations



    3. The attempt at a solution

    Hi,:smile:
    Do you know the formula to calculate Time period of a pendulum ?

    Hint:
    Melting of Ice reduces its weight.

    formula of time period is T=2*pi root over l/g
    so how does reduction of weight helps out?....i mean time period is not dependant on mass and gravity remains constant at a particular place (weight =mg)...???

    That is the trick.You almost got it.

    Not sure how that's a hint.

    The period of the pendulum is independent of the bob mass. Ah, Galileo's wonderful discoveries.

    Seems you did not read my next post :p

    so if g remains constant...then there is no effect on time period????
