Homework Statement
Check if the equation is dimensionally correct
The frequency f of vibration of a pendulum of length L is given by the equation:
f = L/2π √(g/L)
I'm assuming 'g' is the gravitation field strength (?), which is [L]1[T]-2
The Attempt at a Solution
[/B]
I did not know what the physical quantity was for f, so i looked up and it was [T]-1
so i did:
[T]-1 = [L] x √([L]1[T]-2/[L])
simply
[T]-1 = [L] x √([T]-2)From here I'm stuck on what to do with that square-root.
