Question 5
John conducts an experiment on fluids using the setup in Figure 5.

The figure labels P and Q as liquid density 1.5 g/cm³, and R and S as liquid density 0.75 g/cm³. The black balls (above P and R) have density 1.0 g/cm³; the grey balls (above Q and S) have density 0.85 g/cm³.
(a) Based on the densities of the balls and the liquids, describe whether each ball will sink or float after being dropped in the cylinder. [2 marks]
(b) Which ball experienced the most pressure after being submerged in the liquid? Explain. [2 marks]
