Theoretical Section: Question 4 A common device used to demonstrate the interaction of charges is an electroscope. An electroscope has a metal conducting sphere or platform open to the environment and is electrically connected to two metal leaves inside an enclosed insulated container. These leaves move on a pivot so that they can open away from each other if they experience a repelling force. A neutral electroscope will be observed to have leaves hanging straight down in a neutral position. If a net positive or negative charge is transferred to the exposed conducting sphere of the electroscope, the excess charge will distribute throughout the sphere, connecting rod, and leaves so that all components have a net charge. As the two leaves now have a net charge of the same sign, and they will repel each other. The diagram below shows the leaf positions of a neutral electroscope and an electroscope with a positive net charge. Arrange + and - signs on the sphere, connecting rod, and leaves of the electroscopes to indicate the charge distribution corresponding to a neutral and positive net charge, similar to what you did in Question 2.
