# EDEXCEL PHYSICS UNIT 6 &gt; HOW WAS IT? watch

1. (Original post by Goddess)
What is the source of centripetal force for the electrn in the bubble chamber?
I said it was the magnetic field strength pulling it or something
2. did people get that the star was moving towards the Earth ??
3. for teh recessional velocity i put that it was 1.36 exp 7 then crossed it out and did 420 -20 so used 400. and got 15 exp somoehting. but i def said towards the earth. on the whole i thought it was a gd phy6 paper.

for the two plates did u draw it so the hoels were lined up or so they werent lined up.
and what did people draw for the very last qu bout finding the work function

also, it was meant to be:

1.5*25/(72K + 25)

No?
no..it was 47k ohms!

so 1.5*25/47025 giving 7.98*10^-4

n yup i got 36.2k for the temp as well....3*10^7 for electrons
n erm wat there was some 1.44*10^7 for something in the first question?

wat were the questionsss..my mind blankin out
dont think it was that bad tho

o but i didnt kno how to measure that tiny current from the electrostatic mill..just made it up
for teh recessional velocity i put that it was 1.36 exp 7 then crossed it out and did 420 -20 so used 400. and got 15 exp somoehting. but i def said towards the earth. on the whole i thought it was a gd phy6 paper.

for the two plates did u draw it so the hoels were lined up or so they werent lined up.
and what did people draw for the very last qu bout finding the work function
i got 1.36*10^7 for the velocity
n i put the holes as not overlapping at all

n the work function thing is in the book..i put the same circuit

I missed the question ?!!&\$# %#! Now I've missed two questions !!!

they were NOT lined up...it told in the info..when lined up theres 0 induced charge...somethin like dat
8. What a strange exam, I finished 40 minutes early!!

Im not going to read, or contribute to this thread anymore, because I dont want to know how I did!!!

No. when they were lined up, max charge was induced.

I said it was the magnetic field strength pulling it or something
I said it is due to two electrons colliding with each other. I'm probably wrong
11. (Original post by sequence123)
One was 47, the other 25

so i did 25/72 times 1.5
wrong as one was 47Kohms
one was 27ohms

it said work out the velocity... velocity has direction..dont worry u'll only lose a mark if u never put the direction

I drew not lined up

im 100% sure they were not lined up ok.
15. (Original post by SinghFello)

nopes..when they were lined up the charge was zero..
i went about thinking about it in my head without realizing it was given in the text

it was a relief to see both theories matched up tho---my head n the text that is

i finnished 30 mins early.

I dunno how idid either, im going to revise c4. This phy6 exam stressed me out so much, im gonna forget about it.

yeah i finished 30mins early as well..
gl with ur c4
i got p6 tmrw
18. my exams r overrrrrrrrr!!!!!!!!!!!! WooooooooooooHooooooooooooo!!!

Gl, all my mates are celebrating exams are over. I got 1 left, which is so annoying.

Good luck!
I'm off to revise with the lil energy i have left
20. few things.... why does the electron make a white path
why did the vane plate have to spin at constand speed.
why was apotential divider quesation worth 4 marks?
a very strange paper indeed !
