Sure …
In sq values as in T2 calc da error:
U’ve eg value 1.03 +_ .02 s u take da sq of 1.05 n subtract da sq of 1.03 4m it .. this ll b ur error… here… 0.0416
Hope u get it
In frac errors as in j10 51 u take frac error of Vo n Io and add dem up n multiply it with ur value as 4 22oHz in dat ppr frac error was 4/75 multiplying it with our value ie 333.33 our uncertainity was 17.78
Now take a look at ppr n tell me whether u can solve it!!!

Could someone upload a piciture for the arrangement of the apparatus for Nov/2007?

^^^ the error bars were to be drawn horizontally not vertically, since the errors are in lengths not resistance...

Heyyy!
Paper 5 Summer 08 Q2 the last partt.
I don't get how to do?

you have the formula R=Ro e^-ρ η x ...& R= 10% or 0.1 ... solve it and you'll get the ans

that's an estimate... for eg if the error bar is +-12 make a point in b/w 11th and 12th block ...

I really don’t think it’s a wise decision to use a pen on the graph since it’s clearly mentioned to use a soft pencil for graphs and diagrams

how about this: (6.2^2)-(5.8^2)
or this: d(max)^2-d(min)^2/2
It's the same thing whatever's easier to remember, it's upto you

can I know the rule u used?
also I got 4.8
the scale on the graph is 5 per the small square so the error bar is waaaaaaaaaaaaaaaaaay too small
am I wrong somewhere?
