Two identical particles each of mass $m$ are separated by a distance $d$. The axis of rotation passes through the midpoint of $d$ and is perpendicular to the length $d$. If $K$ is the rotational kinetic energy of the system,then the angular frequency $\omega$ is:
- A$2d \sqrt{\frac{m}{K}}$
- B$\frac{d}{2} \sqrt{\frac{K}{m}}$
- C$\frac{2}{d} \sqrt{\frac{K}{m}}$
- D$\frac{d}{4} \sqrt{\frac{m}{K}}$
