When you take your laundry out of the dryer, you notice some annoying static cling and wonder how much charge is actually involved here. You remember a textbook problem that seemed quite detached from reality then, but turns out to be useful now: You take two small empty cans out of the recycling bin and place them on the kitchen scale. They each have a mass of 100 g. You tie them together with a string and hang the string over a nail that is sticking out of the wall. The cans are hanging down 40 cm.
