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.

13.1. How can you show by simple experiments that there are two types of electric
charges?
13.2. Describe the method of charging bodies by electrostatic induction.
13.3. How does electrostatic induction differ from charging by friction?
13.4. What is gold leaf electroscope? Discuss its working principle with a labelled
diagram.
13.5. Suppose you have a glass rod which becomes positively charged when you rub it
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.
13.13. What do you mean by the capacitance of a capacitor? Define units of capacitance.
13.14. Derive the formula for the equivalent capacitance for a series combination of a
number of capacitors.
13.15. Discuss different types of capacitors.
13.16. What is difference between variable and fixed type capacitor?
13.17. Enlist some uses of capacitors.
13.18. Discuss one application of static electricity.
13.19. What are hazards of static electricity?
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

Sir i have seen yr videos lecture in maths .physics .chemistry . You are multi talented how you do it👍

[linosofficialjereumi]

Your 'phir sa' is really helpful. AK dafa ma smj AATA ha dosri dafa btaya jae to yad ho jata ha. 10th grade ki physics ma mere highest marks was all because of you. Allah ap ka Lia asania kra.

[abdurrehman]

I wish you teach us in our school 😊 good way

[mahamshakeel]

Thanks alot Sir.This is very helpful to students who are struggling with physics.Your way of explanation explains me the concept in no time.

[aleenayaseen]

Am student of mphil physics and also teacher of class 10 ....my teaching experience is two years but still I prepared my lecture daily and also learned new concept 😂❣️ and your lecture is amazing 😍

[ayeshatahir]

Superb teacher you also tells the sequence of long question

[samsister]

I just love your vedios because there is many concepts in short time thank you so much

[khanidawar]

Mashallah you have good experience and good concept, 👍

Q:-(1)What is the electric field Intnsity inside in the Charge?

[AbidAli-dntf]

Sir your personality is beautiful and you are good

[ndvvfuj]

Your explaination is just amazing !! No one can beat you !!Thankyou sir😊

[abdulhannan]

sir! charges k darmiyan "force" electric field me hi lagy gi ya elecric field sy bahir bhi ho skti h?

[chilimili]

Sir electric field ek vector quantity ha or is ki direction electric field line ki direction mai ho gi ???
