Forces with magnitudes $2\,\text{N}$, $4\,\text{N}$ and $7\,\text{N}$ are combined to give a resultant force. The three force magnitudes are fixed, although the forces can act in any direction within the same plane. Which magnitude is not a possible value for the resultant force?
- A$0\,\text{N}$
- B$5\,\text{N}$
- C$8\,\text{N}$
- D$13\,\text{N}$
