Hanging out. (a) A block of mass m = 20 kg hangs from two cables attached to a ceiling as shown in Figure P4.89A. What is the approximate tension in each cable? Hint: The two cables make the same angle with the vertical direction, but you will have to estimate this angle from the figure. (b) The two cables are now rearranged so that they make different angles with the vertical direction as shown in Figure P4.89B. Estimate the tensions in the two cables.
