http://www.xtremepapers.com/papers/CIE/Cambridge International O Level/Physics (5054)/5054_s04_qp_1.pdf

i think it should be B

 

[Talhakhan]

I was doing past paper for bio ATP and Was doing june 2010 and saw 2 papers 1st variant and 2nd variant,,,,
What is the difference in between these two?????

 

[Talhakhan]

i think it should be B

I also thought it was B but when i saw past paper answer it was given C.....;D

in some countries it is paper 61 and in others it is 62

it is C.
from either direction if you insert N , u'll get deflection in right

Thank u so much for ur help ..... Cheers

But brother won't pushing the north pole in the direction of Q will reverse the induced E.M.F..... THINK,,,,,,,

no problem! glad if i helped....btw welcome!

sorry but my knowledge says that the answer should be D
cuz over here the deflection is towards right, the electrons moved to the left and only if you push the S pole into P , then youll get this deflection...hope i helped...and do correct me if am wrong..

LOL...should have seen this earlier...

what is the answer in the mark scheme? is it the same or different?

 

[Talhakhan]

humm! i have checked it Talha Khan........Fallen sahi keh rahay hain .....it is explained in Federal Physics

Areeba fatima mai federal ki book say hi dekh kar bata raha tha ,,, that we all were wrong ,,, federal ki book mai aik hi tarf kay magnet pull ya push kya ja raha hai ..... But in this question we have to see it from both direction and sides....

In marking scheme C is given.........we thought it was B and examiner report said it is D.........

MashAllah , the only option left was A , we should have tried it as well
there would be quite a variety then
