Calculate the amount if work which a ball bearing of weight 50mN does against the drag force (fluid resistance) when it falls at a constant velocity through 1 metre of fluid. Remember that the fact that the ball bearing is falling at a constant velocity tells us that the resultant force which is acting on it for the duration of the fall is 0.
