A 600-Kg Ornament Is Held at Rest by Two Light Wires

question 57

Multiple Choice

A 6.00-kg ornament is held at rest by two light wires that form angles with the vertical, as shown in the figure. An external force of magnitude F acts vertically downward on the ornament. The tension exerted by each of the two wires is denoted by T . A free-body diagram, showing the four forces that act on the box, is shown in the figure. If the magnitude of force F is 410 N, what is the magnitude of the tension T?

• A) 271 N
• B) 470 N
• C) 235 N
• D) 188 N
• E) 376 N
