p52 physics

[arerule]

omg you will never imagine this question... so effing hardd !!!!

 

[sweet7]

wat wz it????

 

[gerrard]

hall probe

 

[zinnia]

what is hall probe????? it's not in our syllabus.............

 

[mina]

i messed this hall probe question, wat was ur gradient and g in 2nd question

 

[Carry]

Hall probe is clearly give in the syllabus..check unit one.
p5 is an A2 paper ofcourse

 

[gerrard]

g was 965 cm/s^2

 

[zinnia]

value of g was 9.87 and gradient was 4.. I converted cm into m while taking the gradient....will they deduct marks for this???

 

[sweet7]

hall probe!! wat??? im scared....i dono watz gona cum 4 p51.....

 

[atoofa]

t think ppr waz ezi...n any1 who ad done all ppr 5z includn 2002 n 2006 wale would av been able 2 solve da ppr quiet ezily....wat do u say?

 

[gerrard]

no...my gradient was 0.041...well the question was in cm and it should hav been done with that..still best of luck

 

[mak]

yar lst part me percentage err kya tha ? nd tell me k wo jab t ko T me convert karna that to err b 10 se divide karna tha na ?? lyk in the table for first 2 values my err was 0.04 nd 4 other 4, it was 0.03... was it ryt ??
nd mera g b 1017 aya ! errs screwed me !

 

[gerrard]

yeh correct.......last part mine was 6.8 %

 

[pineapple]

My gradient was something like 0.036, and my g value was about 1980 cms^-2..
But how do you find the uncertainty here??? I just used my graph's uncertainty

 

[gerrard]

we had to add the % uncertainty of g and t^2

 

[pineapple]

we had to add the % uncertainty of g and t^2

Oops, I didn't do that!

But the percentage error was something like 7.somethin?

 

[Dara]

My gradient was 0.04 +- 0.02, and g was 987 +-300 something.. :O and error was 8.8%

 

[ramisalah]

any guesses for ppr51 ??

 

[sse2010]

do all da papers frm 02 to 09 for 51...i thot k CIE wnt giv questions like this which appeard in papers before 07, but CIE has gone crazy, do all the papers!

i didn't get yuh quite well but yeah the first 2 values had uncertainity of 0.04 and the remaining 4 of 0.03
