Two Silly calculation mistakes in this lecture.
1) At around 21:50, finding Vac i have taken r =1 but it should be diagonal that is r = root 2 and thus Vac will come out to be 20V.
2 ) In the Questions where We are finding E, ( E = -dV/dx type ) i have done sign mistake that i have not put - sign while differentiating. So all answers are correct in magnitude but sign should be - in all terms. It happend in flow and was repeated in all questions.
I apologise and students should follow the formula and help telling others about it when asked in comment section.

[subhrojyotidas]

21:00 the ans for last one should be -20 again because delta r is √2(Diagonal), hence cos45 will cancel with √2 and we will get -20 as ans...

[creativemaster]

studying lecture of past 4years but still 200times better then todays regular

[surendrakumar]

क्या दूँ गुरु-दक्षिणा, मन ही मन मैं सोचूं
चुका न पाऊं ऋण मैं तेरा, अगर जीवन भी अपना दे दूँ।

[vardaan]

Homework answer :
E (vector) = -(1i +1j + 2k)
E (Magnitude) = root6

[realityofsociety]

#quarantine. I started his lectures even after knowing that my online classes are regular going however they are not good teacher as alak sir

[ruturaj]

42:21
On diffrentiating we will get here as -2
Since Ex = -dv/dx

[nihaalthakker]

time stamps for making notes for theory
1:55 relation between E and DV
5:26 case 1 uniform ef
13:00 question
27:41 case 2 non uniform
39:43 and 41:38 for notes and further questions

[DendrocnideMoroides]

Video starts from "hello kya hal-chal badya ekadam"
And ends with "Padhaye Karte rahe ALL THE VERY BEST "

[tanishprabhavat]

Sir the answer for the homework is:-
E=-1i -1j -2k
[E]=√6
And sir lastly the mistake which you made while taking sign conventions during the partial differentiation is nothing compared to your hardwork, dedication for all of us.... I would personally share my experience. I am a student at aakash institute, when I was in class 11, I couldn't score more than 450 marks in our exams just due to physics...but since when i have started watching your lectures, I have started scoring 600+ with AIR in top 1000 out of 40000 students....so I really thank you...

Further trick application of same trick "Potential always decreases in the direction of field". In equilateral triangle question 1st part 26:23 no need to calculate cos60° because we moved only 1m in direction of field we can calculate | ∆V | = 10×1 = 10V and Va<Vc so ∆V = Va-Vc = -10V . Same for other this type questions 👍

[classroomkafanda]

The most difficult thing in this lecture is to tell my parents that i am watching physics lecture

[doctoripsi]

Homework question's answer is -(i^+j^+2k^) and magnitude of E is √6...thnkuu sir

[aarya]

when he says.. 11th pdhi thi na .. that hit me hard

[RiyaRiya-R]

Thank you so much sir❤🙏🙏🙏
Session 2023-2024

[wwearchitect]

51:15 Answer : E vector = i^ + j^ + 2k^
And, |E| = √6

[gyanendrasharma]

Ans of HW ques-
E= -i^ -j^-2k^
|E|=√6

[shivdama]

51:00 Evector = -1icap -1jcap -2kcap
|E| = root6

[akruthiisbhat]

Sir answer is E=1i+1j+2k
|E|=√6
