Answer: 2.07N
Step-by-step explanation:
∑Fy=4N
∑Fx=0N
The total Tension force on either side must be equal, therefore, Ty+Ty=4N.
Since we are only concerned with the forces in the y direction we will use the sine function.
Ty=Tsinθ
Ty+Ty=2Ty=4N
2Ty=2Tsinθ=4N
Then solve for T, 2Tsinθ=4 ⇒ T= 4/(2sinθ) ⇒ 2.07N
