Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a problem about dimension matchig.

the dimensional relation between the periodτ, the pendul lengthl, and the acceleration of the gravitygtakes 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
