A coin is released from rest and moves downward through the air until it reaches a steady speed. The diagram shows two forces, $P$ and $Q$, acting on the coin so that there is a resultant force. Before the coin attains constant speed, what happens to force $P$ and what happens to the resultant force?
- Aforce $P$ decreases; resultant force increases
- Bforce $P$ decreases; resultant force decreases
- Cforce $P$ increases; resultant force decreases
- Dforce $P$ increases; resultant force increases
