Question

Prelab Problem: You have a parallel plate capacitor with circular plates of radius
r = 10.0 cm separated d = 2.00 mm.
a) What is the capacitance of your capacitor?
b) You need a capacitor with capacitance C = 840 pF, so you wish to modify
your capacitor to get the desired capacitance. You are not able to change the
distance between the plates or the size of the plates, but you could insert an
insulating material between the plates. What should the dielectric constant of
the material be?
Show all your work. First show equations in symbolic form and then substitute for
known quantities to obtain numerical value. Show how the units work out.
