In Figure 13-5 (not to scale), a package of mass m hangs from a short cord that is tied to the wall via cord 1 and to the ceiling via cord 2. Cord 1 is at an angle of = 40° with the horizontal. Cord 2 is at angle (theta).

a. For what value of theta is the tension in cord 2 minimized?(in degrees)

b. In terms of mg, what is the minimum tension in cord 2?
