Shortest period for a physical pendulum

[drunknfox]

Homework Statement

meter stick pivoted at point a from its center and swings as a physical pendulum. At which values of a gives you the shortest period of oscillation...1m, .2m, .3m, .4m. .5m

Homework Equations

T = 2pi*Sqrt(I/mgh)

The Attempt at a Solution

the shortest a should give you the shortest period. The longer the distance = longer period but the answer is .3...why?

hi drunknfox! welcome to pf!

(have a square-root: √ )

the shortest a should give you the shortest period. The longer the distance = longer period but the answer is .3...why?

erm … you tell us!

start by writing out the relevant equations ​
