I usually avoid social distraction and adore isolation with mathematics.

Well, @Rajdeep Dhingra does FIITJEE prepare for RMO and NSEJS?

Log in to reply

It makes U prepare for NSEJS but only a little for RMO.

Log in to reply

Then I should join FIITJEE next year itself!

@Sravanth Chebrolu Hey Sravanth, Have you posted any problems on Projectile motion? Can you post some?

Log in to reply

Yeah. You can check my set Gravity, but presently I am not working much with physics, if you really want some problems I'll post them soon! \(\ddot\smile\)

Log in to reply

Thank you!

Have U tried mine ? Come on Hangouts

I can't come on Hangouts for reasons, and yes I have tried your problems, and the alien Projectile problem was just great!

@Sravanth Chebrolu Hi! Can you please let me know how are you so good at logic? How can I improve?

Log in to reply

I think you must take suggestions from Nihar or Pi Han Goh sir or Calvin sir or Julian Poon sir etc. . .

They are lot better than me!

Log in to reply

Remember the thoughts,

I think these two thinks did help me a lot! But, honestly, I don't think I am so good

Here are some tips to improve yourself:I recommend you to play

chessif you would like to improve at logic.(I personally love playing the game!)You can practice questions on brilliant! That's the best way to improve yourself.

@Nishant Rai Hello again, Sir!

Can you please suggest me some reference books for Class 11 Physics?

Log in to reply

@Swapnil Das

Read

NCERTfirst, as it will , to some extent, help you in your boards.After that, do

NCERT Exemplar. You can get the pdf's from here . It contain's some very good, high level questions.If enrolled in some coaching institute, go through their material thoroughly ( Do not jump form one coaching material to some other, they all contain the same thing, except the way they are written).

Log in to reply

@Swapnil Das

I forgot to mention \(\text{Concepts of Physics Vol I and II - H. C. Verma}\). Do it to clear and test your conceptual understanding of the subject.

Log in to reply

@Swapnil Das After that, go for \(\text{Problems in General Physics - I.E.Irodov}\)

Log in to reply

Log in to reply

@Nishant Rai pls post the solution to the problems. Thanks!

@Swapnil Das to all the questions i have posted??

No Sir, the Kinematics ones up recently posted.

@Nishant Rai Hello Sir! I just wanted to make a humble request. The standard of the problems you post on Brilliant is really great. I just wanted you to post some kinematics problems on B'ant( without trigonometry, but of high standards). Please take my request into consideration, and please help aspiring physicists like me.

Log in to reply

@Swapnil Das Thanks! give me some time, i will surely post questions related to Kinematics.

Log in to reply

Thank you very much!

@Sravanth Chebrolu Hey bro! actually the answer to the second question asking for remainder is 46. It is given in my answer key and I solved it too.

Log in to reply

Can you ex plain that?

Log in to reply

The last expression comes as x^2 -13x + 32 = f(x)

Log in to reply

Log in to reply

Log in to reply

Combinatorics, I see to that very soon! I am building a new set don't miss it!Log in to reply

Log in to reply

Log in to reply

Oh! Yes. Sorry for leading you the wrong way.

The new function is actually, \(f(x):x^2-13x+32\)! And that when divided by \((x+1)\) leaves \(46\).

No sorry in Friendship! ( if you accept me one)
