Tarun sir that it will only take straight lines to solve as in net some integration method is used

Ans is 3388 and as usual my answer is off by a huge margin 🤣 (6pie squared)

My logic : since the cylinder is open we cant Directly apply gauss law so I complete the cylinder with an imaginary half cylinder

Now all the charges whether they are at a,b,c,d lie outside the cylinder( imaginary and closed) so they all irrespective of position should contribute zero net flux

Pls tell the fault in my logic in detail as my physics is weak

Ans is a btw

Bhai iska initially solve Kiya aur b aya phir online check Kiya toh sns d hai aur reason de rahe hain ki low temperature pe elimination nahi substitution hoga

Mere offline centre pe elimination nahi padaya gaya direct ye hua hai to koi explain kardo mechanism with photo of option d

From ra sir assignment

Ans is d and for some reason mine is coming b

Inverse function se karna tha isko par start kese karu
