A board, with a weight mg = 120.0 N and a length of 5.00 m, is supported by two vertical ropes, as shown in the figure. Rope A is connected to one end of the board, and rope B is connected at a distance d = 1.00 m from the other end of the board. A box with a weight Mg = 20.0 N is placed on the board with its center of mass at d = 1.00 m from rope A. What are the tensions in the two ropes?
