A mass of $30\,\text{kg}$ hangs from the lower end of a wire. A horizontal force $F$ acts on the mass so that it remains in equilibrium, while the wire makes an angle of $30^\circ$ to the vertical, as shown. What is the magnitude of $F$?
- A$17\,\text{N}$
- B$150\,\text{N}$
- C$170\,\text{N}$
- D$510\,\text{N}$
