Explain the operation of an electroscope in its simplest form. This answer has not been graded yet. (9) Explain how an electrically charged comb can attract small bits of paper even though the paper is uncharged. This answer has not been graded yet (10) Small bits of paper are attracted to an electrically charged comb, but as soon as they touch the comb they are strongly repelled. Explain this behavior.Explanation / Answer
8)
The suspended strips and the metal rod are able to conduct electricity. The metal rod passes through the jar with a stopper that is not capable of conducting electricity. When a charged object is brought near the metal rod, both strips repel each other and resemble an inverted V. The strips repel each other because they have acquired a like charge. When the strips have a like charge and separate, the electroscope becomes charged. If an object with the opposing charge is brought near the metal rod, the strips of gold leaf will hang straight down. The strips no longer repel each other because the charge has been neutralized. After neutralization, the electroscope becomes discharged. Electroscopes are commonly used in laboratories and industries for experiments and measuring electric currents. Electroscopes can also be used to detect various types of radiation from radioactive material. The electroscope, the first electrical measuring instrument, was invented by British physician William Gilbert. The pith-ball and the gold-leaf electroscopes are the most commonly used simple electroscopes.
