The diagram illustrates an experiment used to find the force acting on a ball due to a horizontal air flow. The ball hangs from a light string and has a weight of $0.15\,\text{N}$. The string is displaced $30^\circ$ from the vertical. The ball is in equilibrium. What is the force on the ball from the air flow?
- A$0.075\,\text{N}$
- B$0.087\,\text{N}$
- C$0.26\,\text{N}$
- D$0.30\,\text{N}$
