It took scientists a long time to discover what lay behind these two types of charges. Ask which type of force is at work between the balloon and the glass rod or comb (a repulsive force). Amuse the students by pushing the balloon first in one direction and then quickly moving the glass rod or comb to the opposite side of the balloon to make it decelerate and then move in the opposite direction. Place the balloon on a nonconducting tabletop, and use the glass rod or comb to repel the balloon and make it roll across the tabletop. A simple demonstration may be to charge a glass rod or comb by rubbing it with wool, silk, or other cloth and then charge an inflated balloon by rubbing it on your shirt or hair.

Prepare a demonstration of static electricity. Figure 18.2 shows how these simple materials can be used to explore the nature of the force between charges. Similarly, two silk cloths rubbed in this manner will repel each other, because both cloths have negative charge. Two glass rods rubbed with silk in this manner will repel one another, because each rod has positive charge on it. Because the glass and silk have opposite charges, they attract one another like clothes that have rubbed together in a dryer. For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged. By convention, we call one type of charge positive and the other type negative. How do we know there are two types of electric charge? When various materials are rubbed together in controlled ways, certain combinations of materials always result in a net charge of one type on one material and a net charge of the opposite type on the other material. A positive charge and a negative charge attract each other. Thus, two positive charges repel each other, as do two negative charges.

Like charges repel each other, and unlike charges attract each other. Electric charge comes in two varieties, which we call positive and negative. This saying is based on electric charge, which is a property of matter that causes objects to attract or repel each other.

1.You may know someone who has an electric personality, which usually means that other people are attracted to this person.

When there is an identical number of positive and negative charges, the negative and positive charges would cancel out each other and the object would become neutral.ДЄpply Now Ask a Question Download Practice Papers Practice Paper for NEET Positive Charge - When an object has a positive charge it means that it has more protons than electrons. Two kinds of electric charges are there :- Negative Charge - When an object has a negative charge it means that it has more electrons than protons. Various properties of charge include the following :. It commonly carried by charge carriers protons and electrons.

The magnitude and direction of the electric field are expressed by E, called electric field strength or electric field intensity.Д®lectric charges are of two types: Positive and Negative. It is an property associated with each point in space when charge is present in any form. It is the property of subatomic particles that experiences a force when put in an electric and magnetic field.
