Detailed explanation and reasoning is required. Broad answer is needed.
When a glass rod is rubbed with silk, the rod becomes positively charged, but when a rubber rod is rubbed with fur, the rubber becomes negatively charged. Suppose you have a charged object but don’t know whether its charge is positive or negative. Explain how you could use a glass rod and a piece of silk to determine the sign of the unknown charge on the object.
