@6:59 The discrete expression lacks something that is covered by the integral. The discrete expression of energy omits terms where i=j, basically where energy at that point due to charge itself. The integral part includes these terms hence discrete formula can be positive or negative but the integral remains positive.
Thank you Sir...
I was thinking when sir will upload videos on electromagnetism...
and luckily you started the course..
What a brilliant problem. NCERT seems to have indicated this concept in the problem 2.22 for quadrupole potential! (Class XII, Physics)
Thank you sir....apke videos ko dekh kisi ko bhi physics se pyar ho jayega.....🙏🙏🙏🙏🙏🙏🙏🙏
Thnkuuu so much sir 👑👑u are the best 👍💯👍💯👍💯👍💯👍💯ur style of study is just amazing🤩🤩🤩

Aapke concept bhot ache se smj aate h sir
Thanku sir 😇🙏
Thank you so much sir 😊
Thankuuu so much.. Sir... Ur classes are veryyyy very nice and easy to grab ideas...❤️❤️ Plss use more English sir....love and respect from kerala❤️
Sir grifith ka question hh jo aapne suru mein
what a wondering teachin process
Sir What are the physical significance of various multipoles?
Thanks sir
Sir why don't you neglect d^2 term during finding potential due to 3 charges or quadrupole?????...
If you neglect you will end up with zero, which of course is not desirable
We neglect terms we don't need for precise details but in case of quadrupole the precise details are relevant and required
