Investigators are exploring ways to treat milk for longer shelf life by using pulsed electric fields to destroy bacterial contamination. One system uses 8.0-cm-diameter circular plates separated by 0.95 cm. The space between the plates is filled with milk, which has a dielectric constant the same as that of water. The plates are briefly charged to 30,000 V. What is the capacitance of the system, and how much charge is on each plate when they are fully charged?
