Question
What do you observe now? Were they charged in the same way or differently? Create a bunch of tiny bits of paper from some scratch paper, and scatter them on a table. Locate as many different types of cloth from your closet or drawers as you can. Cotton, silk, polyester and wool are the most common. Next locate as many different types of plastic pens, like colored ones and clear acrylic ones. If you have a plastic ruler, have that handy too. In a uniform fashion, try as many cloth/plastic combinations you can and see if you can pick up the paper bits. Try to order the combinations by strength, and record them here. What method of charging is this?| How would you explain why some combinations work better than others? How can a charged object pick up a neutrally charged piece of paper? Doesn't the paper require a charge too? Explain what type of charging method this is.Explanation / Answer
1. It is charging by by static electricity.
2. Static electricity is the buildup of electrical charge on an object. This charge can be suddenly discharged (such as when a lightning bolt flashes through the sky) or it can cause two objects to be attracted to one another. Socks fresh out of the dryer that cling together are a good example of this attraction in action. Specifically, static cling is an attraction between two objects with opposite electrical charges, one positive and one negative.
Static electricity can be created by rubbing one object against another object. This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge. For example, when you shuffle your feet across a carpet, electrons can transfer onto you, building up a static charge on your skin. You can suddenly discharge the static charge as a shock when you touch a friend or some objects.
Whereas objects that have opposite charges are attracted to one another (such as clingy, freshly-dried socks), objects that have the same charge repel. This principle is used in making an electroscope, which is a scientific instrument that detects electrical charges.
3. When we bring a charged object near pieces of paper the charge get induced on paper and hence the attraction. This is charging by induction.
