Answer: 3.36 N
Step-by-step explanation:
The weight of the body acting downwards is balanced by the sine components of the tension acting in the upward direction. The cosine components balance each other.
We just have to find weight, so will calculate only sine component.
Fg = 2 T sin θ
T = 3.7 N
θ = 27°
⇒ Fg = 2 × 3.7 N × sin 27° = 3.36 N
Thus, the body held by two wires having tension 3.7 N suspended from a rigid support at an angle 27° has weight = 3.36 N
