A 6 kg box is held at rest by two ropes that form 30° angles with the vertical. An external
force F acts vertically downward on the box. The force exerted by each of the
two ropes is denoted by T. A force diagram, showing the four forces that act
on the box in equilibrium, is shown in the figure. The magnitude of force F is
410 N. What is the magnitude of force T.
