99sir apart from q1 ive some serious doubts not kiddin these are some thought provokin ones and genuine
kindly consider them and reevaluate if possible
3)M=7 , uve ignored -2Î
27) ans is 100/.19 ln2 uve given E loss proportional to e were its proportional to e2
33) option a is rong there
47) ans comes to be 2 uve neglected motion of lift therafter . lift again comes in contact wen h=2
53) option a is correct
59) for given amt of gas V is prop to T/P , if V inc Tdec.pinc impossible
if ive gone rong kindly correct me
on the whole certain q were superbly thought provoking thanks for a nice test
i feel we should rope in more ppl to participate
1in ques no.23 x>o so we can assume some large no. which will give option c.and according to the ques we can assume any arbitrary value.
1bhaiya becl2can exist in dimer form. actually for ques no.21 i gave ans 1/2 and correct ans is 1/2 but i got negative.and in ques 23 if we take x=56.7 then ans should be c. for ques9 a and asinx for taking the value a=1 the option should satisfy the ques.
62@Celestine:
3) At -2pi.. there is no discontinuity!!
27) I didn not understand ... I have not said that e is the coefficient of restitution!!! (When did i said e was that :O)
33) a is correct
47) I thought that was obvious! (Bcos then the answer will be infinity... the lift will keep moving up forever!) (May be i should have made that more explicit)
53) Corrected
59) corrected! :)
62yeah 13 is wrong priyam.. already marked...
Too many mistakes this time.. 4-5
have to be very careful next time..
I hope first test is forgiven ;)
927) what is e
33) how can a be correct, they interchange their v and not go back with same v
47) but i thought i had to assume max height after first collision ( u gave for 5 marks so thought in detail ;)
and 3 it was my mistake;(
6222.. was alread corrected :)
in 27) i messed with the question.. i meant ratio of energies.. never wrote it and realised that u assumed it to be e.. so the answer is none of these :(
Too many mistakes in this one.. Pakka not in the next test.. u did a good job man :) But i think you need to do better.. u scored 100+ which was good.. But I felt that it was not that difficult..
U have any comments or feedbacks?
(I will fix that 27 in the mean time)
9i ve one more last doubt in q 7
for rolles thm to be applicable btw any a,b shouldnt f(a)=f(b)
62yeah there we have none of these as the answers...
I wanted to give LMVT.. but i wrote Rolle's :D
Anyways.. I will be much more careful from the next time.. or else I will have to start copying questions rather than trying to make myself :D
9sir the test was very fundamental and tested basic concepts to nice level including seemingly simple but tricky ones .
next time make it tougher and i think u shuld advt these tests thru other websites.
i think u can give subjectwise analysis
it was a nice paper to solve
9chem dint involve much of twists like maths and phy
all test series give easy chem ones
could u give a highly twisted chem paper
62lol.. thanks celestine..
You know what i was thinking of making easier papers..
The average score is 19!!!!!!!!!!! (Even if i assume that out of the 98 ppl who attempted.. only 20 gave it seriously!) Evn then it is like 60/225!!!
only 2 got above 100 on a score of 225 odd..
But ok.. i will try to keep it of similar level if not tougher!
Actually the first maths paper I made was a bomb.. I changed it like around 10 questions to bring down the toughness!
9but then the more bombs u put more attractive the pape becums

62haha.. ok yeah u are right.. din update the scores there..
A couple of more corrections are due.. I thought wud do that together :)
9oh yes its schoolexam season
so most will take this test not so seriously
and one more suggestion the paper was no way 3hr paper , make it lenghthier
33[3] sorry!! next time i'll be serious actually tried it without a pen....
I just solved one lift question and Q32 with pen and that too on my hand :P
do tin bar line kat gaya tha na isliye man nahi kar raha tha....
Next time i'll try my best....
1
a+4r=a√2
=>4R+4r = 4R√2
=>r/R = 0.414
may be i am wrong... but cudn find where ?... plz help me out...
another one doubt is q.no.59.... plz explain how 'a' and 'd' are possible...
1357This unit cell can be seen as eight simple cubic unit of edge length a/2
If you have found that you have done the all three question in a minute.
so considering one simple cubic unit cell the void should be at body centre
so we get
2R=a/2
and 2R+2r=√3a/2
1Excellent work by administrators of this site. Sincere applause for their efforts.
I think this test tested the basic concepts well. My suggestion would be to have tests with similar basic premise though toughness levels could vary. Also, as more people give the tests, the scores would become more relevant. As of now percentile could be slightly misleading.
But depending upon the toughness of the tests and your collective experience, could you please also give an indicative Marks Scale corresponding to every, say, 1000 potential ranks for each test? This could be very useful for us participants.
1@manish bhaiya,,
am sry.. i dun get you :(
ur method is okay.. i understand dat...
but y will i find it out dat way... wats wrong in my method ?...
from this also ans should come .. isnt it ?
1areyyyyy yes yes u are r8.. (ofcourse u wre)
but i found my mistake actually..
its ok... it cudn be done the way i did it...
9some more doubts with test
44) wont tot Energy depend on g . (like suddenly earths g inc , its tot Energy changes)
37) strictly speaking there is some minute transfer of KE even wen friction is 0
9ans to first q is -1/2 :)
in cosX-1/2X = -2sin2x/2/x = -1/2
it can also be obtained as sinX = X - X2/2 ......
62Celestine.. today am busy for the tommorow's test.. still a few questions to be made...
So sorry for the delay.. I will look into it..
I think 44 is incorrect! (But i din get the time to change the scores..
There were 3 incorrect questions.. and i guess 3 incorrect answers..
I hope we are able to give question papers without flaws.. but then that is a really tough thing to do :) :D
Sometimes the typos creep in.. and sometimes our minds get poisoned ;)
1ist answer is d
i think pls chek limit dont exist as lhs an rhs r not equallllllll
pls chekkkk
1i have problems with q nos. 1 , 7, 13, 21, 38.
ans 0f 21 has to be x/2 and not 1/2.
for q.no.7, how logx n |x| giving rolles theorem in those intervals? no where f(a)=f(b).
and q.no.5 and q.no.13 are contradicting each other.. if we go by 13.. then ans will be -6 for q.5...
and in 38, while walking,,, friction acts on both the feet...
