A diving-board with uniform mass distribution is supported by two fixed rods at points P and Q. A person is standing at the end R of the diving-board, as illustrated. The forces produced by the rods on the board are vertical. The board stays in equilibrium while the person gradually moves from R towards point Q. Which row shows how the forces produced by the rods on the board change?
- Aforce at P decreases; force at Q decreases
- Bforce at P decreases; force at Q increases
- Cforce at P increases; force at Q decreases
- Dforce at P increases; force at Q increases
