Need Your help to solve this Physics problem!  

One key thing to understand here is that in three dimensions, there isn’t any symmetry to rely on. In the case of two charges, we frequently use solid angles when considering them because their symmetry tells that the behavior is uniform in every direction from the line joining them. However when we return to considering three charges, for each charge a different plane is defined. Everything in that particular plane is not what happens in any other plane. This could be a very nice explanation but in “your frame” where you see field lines coming out from charges might not seem the same going out of charge in another orientation. But if you say that each charge emits N lines, notice that this amount will not be just Q/ϵ because the lines spread out to every direction, including perpendicular to the screen. Therefore, N is just a dimensionless proportional factor in this two dimensional problem. This has been addressed by PHYSICS SIR JEE - JANARDHAN in one of his videos for " ANGLE OF DEVIATION OF A FIELD LINE " as well. I would recommend watching it.

I think its genuinely very obvious it is very fundamental just as( 1+1=2) A single question can't be rated good just becoz you somehow stuck there

Yes, it will be proportional... I've taken a hypothetical hollow sphere around the charge q and intersected it through a plane passing through q... Now, if the plane also has some negligible thickness, then using solid angle concept, the flux through plane comes out to be Q/2Epsilon0 Which implies direct proportionality of flux with charge in that planar region

Sir i think ye sawaal 150⁰ vertex angle ka cone leke solid angle se solve hua h indirectly jese vo question hota h 2 opposite charge wala line alpha angle pe nikli beeta angle pe enter hui... Further hum shayad agar ye prove kr de ki plane me kisi general point pe electric field strength proportional to charge hogi then BINGO ... btw big fan of your personality and problem solving skills, Sir❤

will ask to saleem Bhaiya 🔥

Sir, can I be your thumbnail designer? :)

Great video, ISAC Learning (NMS Sir). Looking forward to your next upload! I smashed the thumbs up button on your content. Keep up the fantastic work. I'm curious, how do you think the deviation angle would change if we introduced a fourth charge into the system?

mai uss offline ladke ke dost ka dost hu Mujhe bhi iss qn me doubt tha sir!

sir jee main 2025 ke liye final test series kab launch hogi

ru-vid.com2RaxpEXJkDc?si=XJynBQFL9e9QkthD In this a child used internal force yo change the state of motion or its just shift of centre of mass.

Sir Agar ek point charge se N lines nikalti h , too vo N lines bhi to Har ek 2d plane me equally distribute hongi , too kya iss logic se nhi bool skte ki 2d plane me lines charge Ke proportional hongi .

sir ijrs ka test dediya.... Batch milega ki nhi wo kese pata chalega??

How can i also send you question related to physics sir?? Please reply..

Sir ap ashsish Arora or insp nitin sachan sir ke bare mein kya opinion denge????

Sir apne Bs dono cases me Field lines equate kri h? Though in case 1 ,u used EFL from single charge And in second case used Efl from all 3 charges Did u use only Angle proportionality and not Charge proportionality?
