Well did you ever come across any question like Q7 from our paper. We've never had 3 particles as far as I remember. if the answer is 71.3 i'll be getting a few marks more. And I'm not trying to fight here sorry If I sounded rude tho.
But their logic kinda makes sense.

I am sorry if I sounded rude too :'(
Well, there has never been a question like Q7 either. However there have been many questions like Q4.

I haev 7 people waiting in line ready to testify that the answer is correct.

Well, i wouldn't be surprised if u had more I mean, it SHOULD be correct. Good going, anyways.

Okay dude, that is literally the most retarded thing I have heard. You cant just subtract time and then make it into limits. Haven't you solved past papers or anything? It was 71.3

What's the difference?

What's the difference?

yar its basicaly cosX=B/H so to find X you need to do X=cos^-1(B/H) but majically my brain malfunctioned and i worte X=cos(B/H) i used a wrong formulae

Guyz for the q with the string attached to A and to B is the mass considered as i didnt use it and used the three forces given to get the t1 and t2 using lamis rule....so am i correct or wrong, and if wrong will i loose all the marks in that question. Thank you!

Does anyone remember question 2, I got 8 for my answer, why did they ask you to find again?

 

[wizteddy13]

Ok, guys, lets just calm down, I'll try and explain why the answer is not 71.3 in the next post.

 

[Oishee Asif]

LOOK.
THE INTEGRATION QUESTION WAS ONLY 3-4 MARKS.
IF WE REALLY HAD TO "FIND" THE NEW LIMITS, IT WOULD'VE BEEN 5 MARKS.
BECAUSE THAT'S ONE M MARK.
