Sir for a sheet we consider surface charge density in one side but for a plate we consider sigma for both sides.. there is slight difference of thickness. That's why we multiply 2 for a plate. Thickness of a sheet goes to zero.
The charges are one side of the sheet for insulator . I mean the charges are in one surface of the plate not in two surfaces. Then why we consider Electric field in two side of the plate or sheet for insulator in the proof? Can a Electric field line pass through inside of the sheet of insulator?Would you please explain it to me.
Sir at 9:51 humlog jo cuboid draw kiye hn to sir dono cuboid same in length breadth height honge ? Agar nhi to sir dono side humlog electric field ko equal kaise kar sakte hn ?
I Think Length Breadth Same Honge, Par Height Different Honese Vi Chalega, Kyuki Electric Flux = {(Surface Charge Density) * (Area)} / €o , (Equation 1) . So, Surface Charge Density To Dono Sides Me Same Hi Honge, Aur €o Bhi, Ab Baari Ayi Area Ki, Area To (Length * Breadth) Hai, Ussme Height Term To Hai Hi Nahi!! Aur Upar Ke Equation 1 Se Pata Chalta Hai Ki, Electric Flux Toh (Sigma, Aur Area) Pe Directly Proportional Hai.... Isiliye, Electric Flux Height Pe Depend Nahi Karta, Agar Equation 1 Me, Area Ki Jagah Volume Hota Toh Hum Height Ko Beech Me Laa Sakte The As Volume Depends On Height Too!! Par Kyuki Area Hai, Isiliye Hume Height Ki Fikar Karne Ki Jarurat Nahi!! Aur As We Can Already Observe That Wo Do Cuboid Milke Toh Ek Bara Cuboid Bann Raha Hai To Uske Side Surfaces Ke Area Toh Ek Hi Honge, Height Pe Electric Flux Depend Nahi Karega, Isiliye, As Long As Area, Sigma, And €o Are Equal In Both Cases, We Can Say That Φ1 And Φ2 Are Equal!! Thank You For Your Precious Time!! And Hope You Have A Very Beautiful Day!! Aur Mai Hope Karta Hu Ki Maine Aapki Doubt Zyada Se Zyada Clear Kar Diya Ho!! Thank You!!
Sir if we considered that sheet as non conducting sheet (very thin) then i think so charge lies inside the sheet or only one side ...electric field can penetrate both side of sheet ...so electric density is charge divided by surface ....my point of view plz reply..
A plane sheet of charge does not mean plane charge conducting plate. A plane charged conducting plate is equivalent to two plane sheet of charge. In this case, the expression is the same as you derived. E=σ/ε0 But in NCERT the equation obtained ( E=σ/2ε0) is for the plane sheet of charge if I am not wrong. Sir, please reply.
Sir plane ka definition he, we choose two pts on the surface in such way that line joining them is entirely lie on the surface...so isme ek he surface he....agar isme 2 surface hota to plane ka definition fail ho jata....
डियर सर,I think NCERT Concept is Right because, राइट साइड में आपने चार्ज को डबल किया यानि कि दोनों तरफ का चार्ज जोड़ दिया परन्तु दोनों तरफ के लिए दो बार epsilon note से भी तो divide होगा क्योंकि दोनों तरफ का चार्ज के बीच में डिस्टेंस है और दोनों की डायरेक्शन भी अलग अलग है i.e. Q/E° + Q/E°=Q/E°. परन्तु फिर इसके लिए भी हमें दो अलग अलग गौसिन सर्फेस भी कंसीडर करने होंगे। या फिर ये भी इमेजिनेशन हो सकता कि दोनों तरफ का टोटल चार्ज Q है। Also, लेफ्ट साइड में भी हम दोनों तरफ का फ्लक्स अलग अलग कंसीडर करके जोड़ रहे हैं। Also, Cylinder के केस में जब इलेक्ट्रिक फील्ड parallel होती है दोनों सर्कुलर साइड के तब भी हम दोनों तरफ का टोटल चार्ज Q ही लेते हैं नाकि 2Q.

Sir I am from Bangladesh. I love how you describe and feel us everything. I have a question. The charges are one side of the plate for insulator. I mean the charges are in one surface of the plate not in two surfaces. Then why NCERT consider Electric field in two side of the plate or sheet for insulator in the proof?

NCERT might have considered charging of the surfaces of the insulator separately. Separately we can charge both the sides of the insulator.Our main aim is to charge in such a manner so that the charge density is sigma in both conductor and insulator. Then the field strength is sigma/epsilon for conductor and sigma/2.epsilon for insulator.
But sir ye sheet conducting hae ya insulating ?agar conducting sheet hae tabhi charge dono side mae reside karega agar insulator hae to charge to ek hi surface pe exist karega .plz sir reply dena waiting for your answer
@@jalalahmedchowdhury7863 as insulator does not conduct electricity and hence the charges remain there without any movement,unlike conductor. I Hope it helps.

But what is the difference b/w sheet and plate ?

Sir 1st case sigma/Eo is for conducting plance sheet of charge and 2nd sigma/2Eo is for non conducting plane sheet of charge......
You have viewers in Pakistan also 💞

But in NCERT the equation obtained ( E=σ/2ε0) is for the plane sheet of charge if I am not wrong. Sir, please reply.
But sir we are finding E. F. only on P so then can't we assume only one side of the plane sheet ? Please reply sir, I'm waiting .

Vry nice sir g
Sir plzz clear my concept:
Why the electric filed near the sheet is independent of the distance from the sheet?
Near the sheet flux density is constant
😀😀😀
What I think
Sir NCERT solve this sheet for conducting plate and you solved for non conducting sheet that's why they are different

please consider a thin sheet having only one surface not a thick sheet having two surfaces. you are making a fundamental mistake... thin means thin
Can You please elaborate?
