A thin circular ring with a radius of $0\mathrm{.}24$ m is hanging from a nail at a point on its outer edge. You give the ring a small nudge so that it oscillates back and forth through small angle. What is the angular frequency of this oscillation?

$4\mathrm{.}5ra\frac{d}{s}$

$2\mathrm{.}4ra\frac{d}{s}$

$5\mathrm{.}2ra\frac{d}{s}$

$7\mathrm{.}2ra\frac{d}{s}$

$3\mathrm{.}5ra\frac{d}{s}$
