Rod XY is uniform and has a weight of $2.0\,\text{N}$; its length is $80\,\text{cm}$. The rod is supported by a thread attached $20\,\text{cm}$ from end X. A $5.0\,\text{N}$ weight is hung from end X. A student places a $6.0\,\text{N}$ weight on the rod so that equilibrium is obtained. How far from end X is the $6.0\,\text{N}$ weight?
- A$6\,\text{cm}$
- B$10\,\text{cm}$
- C$26\,\text{cm}$
- D$30\,\text{cm}$
