When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
Q. What will happen if one plastic rod is rubbed with another?
none of the above Q21.1 Page 2 When you rub a plastic rod with fur, the plastic rod becomes negatively charged and the fur becomes positively charged. As a consequence of rubbing the rod with the fur, A. the rod and fur both gain mass. the rod loses mass and the fur gains mass.

Q. What happens when a plastic rod is rubbed with a dry cloth?
If you rub a polythene rod with a woolen cloth, electrons are transferred from wool towards the surface of the polythene rod. While the dry cloth gains the electrons lost from the the perspex rod. This means that the dry cloth has more negative charges than positive charges and so it becomes negatively charged.
Q. Why do I generate so much static?
Static occurs when electric charges accumulate on an object’s surface; this is commonly a result of two materials that are moving apart or rubbing together. Very dry air and cold weather increases static electricity, so static shock takes place more often in the winter when the air is especially dry.
Q. Why do we need to discharge your body before touching the computer components?
To prevent ESD damage, you should discharge static electricity from your body before you interact with any of your computer’s internal electronic components, such as a memory module. Handle all electrostatic sensitive components in a static-safe area.
Q. What happens to charge when static discharge occurs?
Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. The rubbing of certain materials against one another can transfer negative charges, or electrons.
