The diagram depicts a plank resting in equilibrium on a pivot. Three forces $F$, $P$ and $Q$ are applied to the plank, as indicated. The force $F$ is made larger, but it still acts at the same distance from the pivot. The plank is then no longer in balance. Which alteration could restore equilibrium to the plank?
- Adecrease $Q$
- Bincrease $P$
- Cmove $P$ further from the pivot
- Dmove $Q$ further from the pivot
