Deletedear sir,

Deletei teach physics to 11th and 12th class. and i wanna become the best teacher for IIT PHYSICS, even though, i myself was not able to get admission in any decent engineering college.

sir i wanna ask you, is it possible?? if yes then how? which books will be enough to be a master of things.

your reply matters me a lot sir.

email id- sankalpgupta60@gmail.com

Mr. Krishna, I am ready to contribute in completing this noble work of yours to upload the solutions to Irodov's problems. Please feel free to contact me: gauravgalileikm@gmail.com

Deletefirst of all thanks for improving my physics.I wonder would you please prove this for me coz my physics is very weak.any equation y=f(t-bx) represents a harmonic wave if d2y/dt2 = v2 d2y/dx2. hemant

ReplyDeletethank u Mr.Krishna Kant Chintalapudi, I have been searching for irodov solutions for a long time.. but i could'nt get solutions which explained, how to do a problem.

ReplyDeleteThank u vey much... and please keep posting

ReplyDeletethank you sir vry much for solution it helped me a lot

ReplyDeletego on with good work. your solutions are great.can you give solutions about optics, magnetics also .it would help me a lot

ReplyDeletehow can i solve the i e irodov probles

ReplyDeletesir i want solution of ex 3.2 Conductors and Dielectrics In An Electric Field

ReplyDeletegreat now i am sure to become an iitian.

ReplyDeleteThank u sir for making this solution.

ReplyDeletePlease make it in word or pdf document.

Thanks

sir can u please solve d rest of oscillations prob as fast as u can...pleeeaaaaasssssseeeee

ReplyDeletesir thanku very much.

ReplyDeletemay i know from which class ur interest for physics grew and what is your profession

Pls solve the entire book and give us a deep insight into the problem solving techniques

ReplyDeleteYour solutions r quite helpful.please solve the remaining problems as soon as possible nd i wanted 2 know about the problems in Irodov which doesn't correspond 2 IITJEE syllabus-i think there r many.thanx a lot

ReplyDeletei think the solution to 1.335 given by you has some inconsistancies because if h3 < 3(h2 - h1)

ReplyDeletethen the velocity is imaginary iethe flow stops much earlier within the tube.

The data given in irodov is such that if your solution is correct the answer is imaginary.

though i very much doubt the hint given by mister irodov himself as it is not explicit,but your ans if true should also deal with the cases whence the ans is imaginary separately.

thank you.

Hi ,

ReplyDeleteThe solution of irodov is explained well by you mathematically as well as theoretically - but you have not taken special possible mathematical cases of a particular problem -

Regarding different possible graphical analysis.

You have done a great job, Sir.

ReplyDeleteThanks a lot.

thanks for these sols,,can u pleze put furthur solutions of SHM

ReplyDeletecriusly u have done a great job.....usin 3d models helpd us 2 visualize some of d tricky problems...

Hello, sir!

ReplyDeleteIf you are still maintaining this blog, would you mind fixing the link to problem 1.19 and 1.18? :)

You are really great..

ReplyDeleteCan you pls provide the HC Verma solution. Pls I will be greatful to you

ReplyDeleteWhy do u need h c verma solutions.. It is damn easy...

DeleteBetter don't discourage other people, we all know HC Verma is tough!

Deletesir, please tell me which book to go for theory for solving irodov, and crack iit. please reply.

ReplyDeleteThank you.

sir can u tell me as to how to approach various physics problems ...please

ReplyDeleteIs there only one Irodov book?

ReplyDeleteI guess yes 'the problems in general physics' there may be more by him but this is the famous one and it is published by various publishers like arihant,reem publications etc.

DeleteSir, plz post further solutions for capacitance and Kirchhoff's laws topics

sir,

ReplyDeleteits my humble request to you that can't we have a general proof for electrostatic energy density which is in scope of a 12th class student preparing for iit jee using vectors and calculus. I have been unable to find general proof for it . In hc verma also it is only verified by assuming a particular case for capacitor. I will be thankful to you as there is very less explanation about this energy in many books

try out feynman lectures(volume 2)....gives u a proper proof of electrostatic energy density....but it uses vector calculus(which is beyond the course of iitjee)

DeleteSIR I AM VERY GRATEFUL TO YOU! THANK YOU SOO MUCH ! IM PRESENTLY IN 11TH AND I AM DETERMINED TO GET INTO IIT!

you lie, no one can have such a mind.

ReplyDeletei am sure you must have solved irodov while at iit

you mean fellow.

i got the solution of the problem 4.17 by

ReplyDeleteequating w*w*x=acceleration so

obtained and by doing some

approximations. but answer is not

matching with the answer given in

book.

answer given in book is dimensionally wrong

Deletei also obtained the same answer as

ReplyDeleteyou obtained. But according to the

edition of my irodov there is a

difference of factor of square root

of 2. I request you to confirm the

answer

sir , can u plz give the complete solutions of waves and oscillations

ReplyDeleteplze see http://irodovphysicssolutionrks.blogspot.in/p/irodov-solution.html
