Consider a sheet of paper with a thickness of 0.1 mm and a dielectric constant of 3. Suppose we would like to make a 1 F capacitor using this sheet as a spacer between two metallic plates.

Suppose we took out the paper dielectric (while keeping somehow the distance between the plates the same).

1.26: What is the charge after the paper sheet is out completely?

1.27: What is voltage across the capacitor after the paper sheet is out completely?

1.28: How much work does it take to remove the sheet? Explain the sign of your answer.

1.29: How will the answer to 1.28 change is the capacitor remains connected to the 1V battery during the sheet removal.

A typical thickness for a sheet of paper is 0.004 inches. If you fold a sheet of paper once, the thickness of the folded paper will double to a value of 0.008 inches. A second fold will result in a folded thickness of 0.016 inches. Create a spreadsheet that shows the number of folds from 0 to 50 and the resulting thickness of each fold. Calculate the resulting thickness in units of inches, feet, and miles.
