Question

To better understand the concept of static equilibrium a laboratory procedure asks the student to make a calculation before performing the experiment. The apparatus consists of a round level table in the center of which is a massless ring. There are three strings tied to different spots on the ring. Each string passes parallel over the table and is individually strung over a frictionless pulley (there are three pulleys) where a mass is hung. The table is degree marked to indicate the position or angle of each string There is a mass m1 149 g located at 01 -22.59 and a second mass m2 219 g located at 82 -291° Calculate the mass m3 in grams, and location (in degrees), θ3, which will balance the system and the ring will remain stationary O a 262 g and 34.3° b. 262 g and 145.70 oc. 322 g and 340 od. 322 g and 145.7
