Queries solved in this video
1. What is Electrostatic induction?
2. What is electrostatics ?
3. How can we charge a body by electrostatic induction?
rom these activities, we conclude that:
1. Charge is a basic property of a material body due to
which it attracts or repels another object.
2. Friction produces two different types of charge on
different materials (such as glass and plastic).
3. Like charges always repel each other.
4. Unlike charges always attract each other.
5. Repulsion is the sure test of charge on a body.

with wool. Describe how would you charge the electroscope (i) negatively
(ii) positively.
13.6. With the help of electroscope how you can find presence of charge on a body.
13.7. Describe how you would determine the nature of the charge on a body by using
electroscope.
13.8. Explain Coulomb's law of electrostatics and write its mathematical form.
13.9. What is meant by electric field and electric intensity?
13.10. Is electric intensity a vector quantity? What will be its direction?
13.11. How would you define potential difference between two points? Define its unit.
13.12. Show that potential difference can be described as energy transfer per unit
charge between the two points.

CONCEPTUAL QUESTIONS
13.1. An electrified rod attracts pieces of paper. After a while these pieces fly away! Why?
13.2. How much negative charge has been removed from a positively charged
–11 electroscope, if it has a charge of 7.5 × 10 C?
13.3. In what direction will a positively charged particle move in an electric field?
13.4. Does each capacitor carry equal charge in series combination? Explain.
13.5. Each capacitor in parallel combination has equal potential difference between its

Activity 13.1. Take a plastic rod. Rub it with fur and suspend it
horizontally by a silk thread (Fig. 13.2 ). Now take another
plastic rod and rub it with fur and bring near to the suspended
rod. We will observe that both the rods will repel each other.
It means during the rubbing both the rods were charged.
Activity 13.2. Now take a glass rod and rub it with silk and
suspend it horizontally. When we bring the plastic rod rubbed
with fur near to the suspended glass rod, we observe that
both the rods attract each other (Fig. 13.3).
In the first activity, both rods are of plastic and both of them
have been rubbed with fur. Therefore, we assume that charge
on both rods would be of the same kind.
In the second activity, rods are unlike and their attraction
implies that charges on two rods are not of the same kind but
