A sphere falls from rest through the air. The graph shows the variation with time of the sphere's velocity. Which diagram shows the forces acting on the sphere when it is at the velocity corresponding to point P on the graph?

1. Aair resistance (upward arrow, longer than weight) and weight (downward arrow)
2. Bweight only (downward arrow)
3. Cair resistance (upward arrow, shorter than weight) and weight (downward arrow)
4. Dair resistance (upward arrow, equal in length to weight) and weight (downward arrow)
