Question 6
An object experiences a lift force when it is either floating or sinking into the water. The magnitude of lift force is proportional to the volume of liquid being replaced by the object. A picture below shows the graph of the lift force exerted on a solid cylinder as it is sinking vertically into the liquid. After it fully submerges into the water, the lift force become constant.
If we change the object to a “solid sphere” which can sink into the water. Draw a graph that shows the lift force on the sinking sphere as a function of depth. (2 points)
