The figure shows a system of four strings in equilibrium. Different masses hang from the three pulleys. The mass attached to the horizontal string is 150 g (the pulley support is attached to the base of the stand.) The mass above it is 90 g, and the angle between the first two strings is 60 degrees. The mass above the eye hook attached to the base is 75 g, and the angle between the second and third strings is 70 degrees. (The top two pulleys are hanging from the support bar.) What is the tension and angle of the fourth string attached to the eye hook? Tension can be expressed in grams.
