A ring passes over a fixed horizontal bar. One end of a light inextensible string is fastened to the ring and is used to draw the ring along the bar at a steady speed of $0.5\,\text{m s}^{-1}$. The string stays at a constant angle of $24^{\circ}$ to the bar, and the tension in the string is $6\,\text{N}$ (see diagram).
