A small sheet of aluminium foil measuring 2x 2 cm is charged by rubbing it on some plastic material.
A small sheet of aluminium foil measuring 2x 2 cm is charged by rubbing it on some plastic material. The charge on the small sheet of aluminium foil is then measured and found to be +Q. An uncharged sheet of gold foil measuring 4 x 4 cm is brought close to, but not touching, the sheet of aluminium.
(a) What is the total charge on the sheet of aluminium?
(b) What is the total charge on the sheet of gold? The gold foil and aluminium foil are now allowed to touch before being separated again.
(c) What is the total charge on the sheet of aluminium now?
(d) What is the total charge on the sheet of gold now?
(Note: both aluminium and gold are good conductors)

Create a bunch of tiny bits of paper from some scratch paper, and scatter them on a table. Locate as many different types of cloth from your closet or drawers as you can. Cotton, silk, polyester and wool are the most common. Next locate as many different types of plastic pens, like colored ones and clear acrylic ones. If you have a plastic ruler, have that handy too. In a uniform fashion, try as many cloth/plastic combinations you can and...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
