A solid sphere is released from rest below the surface of a fluid and begins to fall.

Markscheme
Both forces must be suitably labeled.
Do not accept just ‘gravity’
Award [0] if a third force is shown.
Examiners report
The question was generally well answered but many candidates did not realise that the drag force would only be present when the ball starts moving.
