A crane carries a $5800\,\text{N}$ counterweight, placed $2.3\,\text{m}$ from the tower on a horizontal jib. The centre of gravity $P$ of the crane jib is shown. What horizontal distance must separate the $2300\,\text{N}$ load from $P$ for the moment about $P$ to be zero?
- A$0.91\,\text{m}$
- B$3.5\,\text{m}$
- C$5.8\,\text{m}$
- D$8.1\,\text{m}$
