You are performing an experiment using the force table shown in the image at right. The string through which tension force 1 acts has a mass of 0.4 kg suspended from it at an angle of 165 relative to the "x" axis or 0 degree mark as shown in the image. The string through which tension force 2 acts has a mass of 1 kg-suspended from it at an angle of 240. What is the m_agn_it_u of tension force 3 (not shown on the image) that is required to achieve static equilibrium? Though you are giving your result in units of Newtons, please do not include "N" in symbol or word in your answer. Otherwise, your answer will be counted as incorrect. Please enter numerical answers only. Give your answer to 2 sig. gs
