Sir pls explain this question as well(only if it's important)... A free pith ball 'A' of 8g carries a +ve charge of 5x10^-8 C.What must be the nature and magnitude of charge that should be given to a second pith ball 'B' fixed 5cm below the former ball so that the upper ball is stationary? Reply ASAP pls
18:39 mai hr ek charge pe same kaise lgega jb dusre side stored charge badhte jaa rha h to repulsion bhi badhega na to energy applied bhi badhna chaiye? Plz reply
Correct me if I'm wrong.😉 Battery has a potential difference of 10V it will start discharge to 0 Volt. 10V battery 10 to Zero When 10j of energy spent by us(emf or dynamo) and stored by the charges to pass from inside the battery towards positive rod to negative rod with using this 10j energy potential difference is 10v 10-0=10v Inside the battery charges go under tension (pressure on charges) due to chemical forces inside the battery a Electrolyte solution which dissolves inside the battery and it's positive ions goes to positive rod and the negative ions goes to negative rod. And due to Electrical force between two same charges the chemical force decreases and repel near their respective rods and move back to the middle of the battery and when we connect a conducting wire between these two rods then the chemical forces inside the battery decreases and electrical forces increase when the negative charge ions in the wire reach to the positive rod and some of the positive and negative charges reacts and become neutral and these negative charge ions enter from the positive rod because of high electrical force and this negative charges are attracted towards the negative rod and applies pressure towards the negative rod and due to a heavy repulsion force these negative charge ions loses some energy and this energy is stored as potential energy in the negative charge ions and move from positive rod to negative rod with that energy.
Thank you sir. I got 40 out of 70 marks in physics without any coaching just only by watching your videos only and I just watched you from December to February.
Sir there is question in third law we say action and reaction acts on two differrent bodies hence dont cancel each other just in example of ball thrown on wall returns back but how then book resting on table has zero net force i.e how action reaction are cancelled in the case
Naresh Kumar in this case reaction force on book due to table is balanced by the gravitational force of attraction on the book, bcoz they act in opposite directions and hence cancel out...😉😉
Naresh Kumar no, they are not action reaction pairs. Gravitational force on book due to earth is action for gravitational force on earth due to book. This is a separate action reaction pair. Similarly, action on table due to weight of book will have its reaction as the normal reaction on book due to table. Hence, we have two separate pairs of action - reaction.
Dip esh okay but again things are same that gravitaional force of book acts on earth how it is balanced by reactional force by table though both are not acting on same body??
❤️you are love sir. Kitne achhe se concept clear krwa dete hain 🙏🏻🙏🏻😌
You are great Sir. Your lecture is awesome. Please continue.
Gajab sir👌🏻

Reply ASAP pls
Sir आपकी अकादमी कहा है।।
Thank you sir for giving very easy lecture to understand...you are the best teacher..😎 😎
Gajab explanation sir , thankyou so much
Thank you sir because of you I got 85% in CBSE class 12 ..without any tuition..I follows your lecture of physics thank you very much sir..
Amit Mourya v nice
Amazing sir gi
Aapko koti koti naman 🙏🙏🙏🙏🙏
Love you sir kitne acche se concept clear hota hi
18:39 mai hr ek charge pe same kaise lgega jb dusre side stored charge badhte jaa rha h to repulsion bhi badhega na to energy applied bhi badhna chaiye?
Plz reply
Sound is very low in this video
Sir you was a great teacher .thanks for your helpfull efforts which is now clearing our concepts
Thanks sir, I have got 95 marks in physics.
😁❤️
I am from Pakistan ,,,,sir is so amazing.....
Thanks a lot Sir, I passed with 73.2%.Love for you.
I also got 85% in CBSE and I also follows sir physics video

Amit Mourya Great
Awesomeeee
sir am preparing for neet 2019 and am a dropout ,sir aapka 11 and 12 ka playlist ? kha milega
The legend of physics
Gazab sir
Nice 👍👍👍😭😭
sir i pass 12th with 86% only because of you sir
sir you mean that at a point or potential if there is 200v then it will store 200J potential energy
Please upload chapter 3 source of energy of class 10
chemistry ka videos nahi at hai.???
Sir I have a question that if it is given that a battery has 10 volts then how will I calculate charge and work done
Correct me if I'm wrong.😉
Battery has a potential difference of 10V it will start discharge to 0 Volt.
10V battery 10 to Zero
When 10j of energy spent by us(emf or dynamo) and stored by the charges to pass from inside the battery towards positive rod to negative rod with using this 10j energy potential difference is 10v 10-0=10v
Inside the battery charges go under tension (pressure on charges) due to chemical forces inside the battery a Electrolyte solution which dissolves inside the battery and it's positive ions goes to positive rod and the negative ions goes to negative rod. And due to Electrical force between two same charges the chemical force decreases and repel near their respective rods and move back to the middle of the battery and when we connect a conducting wire between these two rods then the chemical forces inside the battery decreases and electrical forces increase when the negative charge ions in the wire reach to the positive rod and some of the positive and negative charges reacts and become neutral and these negative charge ions enter from the positive rod because of high electrical force and this negative charges are attracted towards the negative rod and applies pressure towards the negative rod and due to a heavy repulsion force these negative charge ions loses some energy and this energy is stored as potential energy in the negative charge ions and move from positive rod to negative rod with that energy.
Workdone is 10joule and this was stored as potential difference in the charges V=W/q 10=10/q then q=1

God bless you sir , I was able to score 93 in physics. You made physics interesting for me.
God will bless u sir....nd plz sir thoda fitness or diet pe dhyaan Dijie p lzz sir
Thanks Sir please continue the lecture series of class 10 physics.
I read comments that sir had died in January 2020...is it true ????
Yes 😢
sir physics ki video hindi languge mai upload kijiye plz
Very nice video sir ji
Thank you sir. I got 40 out of 70 marks in physics without any coaching just only by watching your videos only and I just watched you from December to February.
Sir earth ka potential zero q hota ha???
sir when u wil ad more videos of 9th clas
Hii
Bad audio quality sir
Nice sir from Pakistan love you sir
thank you so much
Nice
please send next lectures
Simple and clear explanation.. thanks a lot sir...
sir next lectures

Dip esh can be a reason but still not satisfactory b/c then normal reaction and gravitaional are also action reaction which must not be cancelled
Naresh Kumar no, they are not action reaction pairs. Gravitational force on book due to earth is action for gravitational force on earth due to book. This is a separate action reaction pair.
Similarly, action on table due to weight of book will have its reaction as the normal reaction on book due to table.

Naresh Kumar normal reactional force as well as gravitational force on book due to earth act on the same body(book)
Sir aap great ho sir
