A multilayer film capacitor has a max voltage rating of 100 V and acapacitance of 1.0 microF. It is made from alternating sheetsof metal foil connected together, separated by films of polyesterdielectric. The sheets are 12.0 mm by 14.0 mm and a total thickness of a the capacitor is 6.0 mm (not counting thethickness of the insulator on the outside). The metal foil isactually a very thin layer of metal deposited directly on thedielectric, so most of the thickness of the capacitor is due to thedielectric. The dielectric strength of polyester is 30 x 10^6V/m. Estimate the dielectric constant of the polyestermaterial in the capacitor.
Assume the system rotates in the yz plane about the x axis with an angular speed of 2 rad/s. Find out the moment of inertia of the system about the x axis.
