Hello sir. Just informing you that in Q44 of chem(SB/SX stream), option D does infact have a plus sign, just that printing is a little faint Quoting the answer key: "Option D is Closest, if (-) is change to (+). So, really, the answer is correct(Option D) Even i got it correct :)

in sx q 85 let p(x)=x^2-x+1

ReplyDeletethen P(x)'=2x-1

implies P'(0)=1

p"(X)=2not equal to 0

p(1)=1

Thanks. There seems to be one glitch with the SA key, though- 65 should probably be C, not B.

ReplyDeletetwo of the answers are not correct in my view; these are:

ReplyDeleteQ.65 resonance ans B ; correct answer in my view C

it is simple just calculate B comes 3 + square root 10+ square root 8 = 8.99

option C : 2+ 3square root 5 = 8.77 ; hence C is the shortest path

Q.69 : ur ans B ; correct ans in my view C

Just apply fleming's right hand rule with option C, u can find that only motion in W direction will induce clockwise current

what shud be the cut off? any guess?

can anyone guess this year's SA cut off? is the question easier than last year?
