A spider with a mass of m=4.06×10−5 kg hangs motionless from three stands of web. One strand is vertical, and the other two each make an angle of θ=21.3∘ with the horizontal ceiling, as shown in the diagram. Let Tv be the tension in the vertical strand of the web, and let To be the tension in either of the other strands. In numeric responses, use 9.80m/s2 for the acceleration due to gravity. Write an expression for the tension in a strand that attaches to the ceiling, To�o.
