1PRACTICE PROBLEM
A physics instructor directs three students to pull a ring, as shown in the image. The students have different abilities, hence exerting different pulls. One student applies 4.0 N on the first cable, and a second student exerts 6.0 N on the second cable. Determine the pull a third student must apply on the third cable to keep the ring stationary. Express the direction as an angle measured from the negative x-axis.
