An object hangs by means of two cords around two rods, as shown. [Figure showing an object suspended by two cords around two rods, with forces F₁, F₂ and angle θ indicated] The object is held in equilibrium by the forces F₁ and F₂. The object weighs 10 N. There is negligible friction between the rods and cords. Angle θ is 90°. Which row of the table gives an angle θ of 90°?

AF₁/N: 4.0, F₂/N: 6.0

BF₁/N: 6.0, F₂/N: 4.0

CF₁/N: 6.0, F₂/N: 8.0

DF₁/N: 8.0, F₂/N: 6.0

✓ Correct answer

C: F₁/N: 6.0, F₂/N: 8.0
