Final answer:
The tension in the string can be found using the equilibrium equation for the x-direction. The tension in the leftmost section of the string is twice the tension in the section adjacent to it.
Step-by-step explanation:
The tension in the string can be found using the equilibrium equation for the x-direction. In this case, the tension T1 in the leftmost section of the string is twice the tension T2 in the section adjacent to it.
Therefore, we can express the tension T1 in terms of the variables m, g, and 0 as:
T1 = 2mgsin(θ)
