Naalayk koe nhi hota. Har koe kisi na kisi cheez main genius hota hai.
Net slow? Kbhi kbhi tou xtremepapers ka server mar jata hai mere paas!

Hota hai. Kbhi kbhi har net operator ka dimagh kharab hojata hai.
Sbse zyada PTCL ka hota hai.

hahahaha nyc one

i still dont get it. total moment is sum of moment. there are two forces(although they have same magnitude and direction but they are different) so why u take only one? i must ask my teacher. Saad Mughal please explain, u r gud at explaining.

 

[Suchal Riaz]

Which (b)?
There are two (b)'s.

i said Q8bi which means "question number 8 ke b part ka second part"

 

[Suchal Riaz]

i remember i wrote his name at end

Einstein Baba Saeen Einstein!

 

[Suchal Riaz]

tell me last question of last page

 

[Saad Mughal]

i said Q8bi which means "question number 8 ke b part ka second part"

I did not see the page numbers! I got confused by the two (b) parts under question 8.

oops i did not see that. i printed these two pages from s11/qp21 so thought why not ask u guys before taking to school

Definition of Moments: Moment is the turning effect of a force.
Here the turning effect of the force is equal at all points, the coil is rotating with equal turning effects all the time.
The two forces are given to confuse you. Its like considering this on a pivot, the two forces are at the same distance with the same force so the overall moment will be the distance * force simply. Hope you understand.

and most last question?

i saw that i wx like it isnt our code right???

 

[Suchal Riaz]

hmm.. but u never know. i read in examiner report that most of the candidates were confused by which factors affected strength of electromagnet. next year they gave more than 3 questions relating to the same thing. they said in 2008 that most candidates were unfimiliar with rotating magnet generator. in s11 they gave a question regarding that.
they try to trick us.
