A 13 N board of uniform density is 5 meters long. It is supported on the left by a string bearing a 4 N upward force. In order to prevent the string from breaking, a person must place an upward force of 9 N at a position along the bottom surface of the board. At what distance from its left edge would they need to place this force in order for the board to be in static equilibrium?
