A sphere falls from rest through the air. The graph shows the variation with time of the sphere's velocity. [graph of velocity against time, curve rising from origin and levelling off, with point P marked on the curve] 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 upwards (longer arrow) and weight downwards (shorter arrow)
2. Bweight downwards only
3. Cair resistance upwards (shorter arrow) and weight downwards (longer arrow)
4. Dair resistance upwards and weight downwards (equal length arrows)
