    Hi,

    I have a problem about dimension matchig.

    the dimensional relation between the period τ , the pendul length l, and the acceleration of the gravity g takes the form:
    [ τ ]=[l^r] [g^s]

    Use the fact that the dimendion of τ is [T], that of l is [L], and that of g is [L/T^2] to show that

    τ is proportional to (l/g)^(1/2)

    I dont get the soltuion right...
    Thank you
