# Electrostatic charges: How to differentiate what is the charge when two materials are rubbed together?

June 16, 2019 / By Darwin
Question: Hi, thank you in advance for coming in to view the question. In Physics, there would be both positive and negative charges produced when materials are rubbed together. My question is, how would you know what charge is produced, is it positive or negative, on that material when rubbed together? Or is it just a pure memory kind of thing. Example, Glass rob rubbed with silk, Positive charge- Glass, Negative charge- Silk. Ebonite rob rubbed with silk, Positive charge- Fur, Negative charge- Ebonite. Rubber balloon rubbed with hair, Positive charge- Hair, Negative charge- Rubber. Hope to get answers from fellow yahoo users soon. Thanks in advance once again. Toodles. To add on, are there any ways to remembering/ memorising the table of charges produced if different materials are rubbed together such as the examples given above?
