A uniform diving-board is held by two fixed rods at points P and Q. A person stands at end R of the diving-board, as shown. The forces exerted by the rods on the board are vertical. The board remains in equilibrium as the person slowly moves towards point Q from end R. Which row describes the changes to the forces exerted by the rods on the board?
