Answer: A body is thrown vertically upwards and returns to the thrower.the direction of fluid friction on the body is vertically downwards during upward journey and vertically upwards during downward journey.

Explanation:

The friction acts always opposite to the motion of the system. The fluid friction resists the motion of fluid. It always acts in the opposite direction. Hence, when the fluid is moving upwards, the fluid friction will act in opposite direction i.e. in downward direction. When fluid flows downwards, the fluid friction would act upwards.

Hence, when a body is thrown vertically upwards and returns to the thrower.the direction of fluid friction on the body is vertically downwards during upward journey and vertically upwards during downward journey.
