1@ Ashish
ya that is also wrong
300 years should be the answer
I was going to come to that
1It was for resistors
energy lost in that case in form of heat
But here no energy is lost
I can prove it also
11No. I think half the energy will always be lost in the connecting wires. I'm just telling out of memory cos I remember that my Phy teacher proved somthing like this but I don't remember whether it was for resistors or capacitors.
106can anyone explain Q48...
I have not read radioactivity chapter
BUT
in 100 yrs 50% will have disintegrated
in next 100 yrs 50% of 50% i.e more 25% will have disintegrated
in next 100 yrs similarly more 12.5% will have disintegrated.
hence in 300 yrs 87.5% will have disintegrated
1yes q.no.104.
wont it be 1/x - 1/2x2 + ln(x/1+x) +c ??
has anyone got this... i did it so nicely [2]
13Q104.....i think it should be ln(x/x+1)+1/x-1/2x2+c
1can someone explain Q81
I got the expression a2sec2θβ/2
so min is a2β/2
but max was asked,so none of these

1have a look at Q81
max was asked that should be ∞
min is wat is given in the answer
106Q80 i think options are wrong.
See f(x+y) = f(x) + f(y)
f(0) = 1
put x=0,
f(0+y) = f(0) + f(y)
f(y) = 1 + f(y)
0=1 ?????
106Can anyone explain how Q71 is done??
How can the sample space be 125, it shud be 36
11but bhaiyyah, i can't think like this in the middle of an exam [11]
even though my solution was 200% correct([3]), my answer is wrong and i get a -1 for it. [2]
