Initially, the wrecking ball A of mass m is held stationary by the horizontal cable AB. The cable AB is then released so that the wrecking ball A starts swinging about the fixed point O. Determine the tension in the cable OA before the cable AB is released and immediately after it is released. What is the percent change in cable tension if θ = 30°?
