A beam is hinged at one end, as illustrated. The beam has a weight of $6.0\,\text{N}$, and this weight acts at point $X$, which is $40\,\text{cm}$ from the pivot. A force of $4.0\,\text{N}$ is applied to the beam so that it remains balanced in a horizontal position. In what direction, and at what point, is the $4.0\,\text{N}$ force applied?
- Avertically downwards at $20\,\text{cm}$ to the left of $X$
- Bvertically downwards at $20\,\text{cm}$ to the right of $X$
- Cvertically upwards at $20\,\text{cm}$ to the left of $X$
- Dvertically upwards at $20\,\text{cm}$ to the right of $X$
