so honest person.... he's just admitting that he don't know the things he don't know....ulike certain someone that pretends to be knowing everything
I really understood it sir thanks 😊👍
D vector only depends on free charge distribution , we can manipulate free charge density easily as compared to bound charge
Thanks sir
5:16 field due to the polarized material ki sides ki field not included why?
11TH PHYSICS NCERT के ACCORDING Displacement शब्द का उपयोग तब हो सकता है 1.जब कोई body time और reference के respect में अपना place बदले
2. एक ही जगह पर किसी physical quantity की value, time के respect में change ho
अगर किसी का स्वभाव भी बदलता है तो हम कह सकते हैं उसके स्वभाव में displacement हो गया।
यहां matarial electrically अपना स्वभाव बदलता है
इसलिए displacement शब्द का उपयोग हुआ है।
why inside dielectric when we want to find the electric field we put epsilon in vacuum? Gauss law says flux through the surface is equal to total charge enclosed by epsilon? inside dielectric epsilon must be different than that of vacuum , i am confused here
I had the same question but then I got to know that Gauss law is actually about q/epsilon(vaccum) be it in any medium. I don't know the reason and still trying to find out why it's the way it is.
Thanks sir 👍
Is this for class 12 th.?
No it is for bsc students first year👩🎓
it is discussed in NCERT Physics 12 Chapter 2. But clearly out of the syllabus.
you can study this if you'll be writing JEE Adv, or Olympiads this year because such topics are quite common in Olympiads.
Thanks sir
Thanks sir
