(a) Referring to the hanging planter in Example 6-10, which of the three graphs (A, B, or C) in FIGURE 6-46 shows an accurate plot of the tensions T1 and T2 as a function of the angle u?
(b) Choose the best explanation from among the following:
I. The two tensions must be equal at some angle between θ = 0 and θ = 90°.
II. T2 is greater than T1 at all angles, and is equal to mg at θ = 90°.
III. T2 is less than T1 at all angles, and is equal to 0 at θ = 90°.
