0.62
For the moment question 0.62 is the wrong answer. If the sphere is uniform then the force acts halfway through it, so 12 + radius =14.5cm. Then it is 0.145×5=0.725Nm, youll probably get 1 mark though

Did anyone get alpha as 10
yeah i did that was a trippy one

What was the phase difference pi/8?
Put pi/4 coat it was 1/8th of a wavelength path difference. thus phase difference was 2pi/8 so that simplifies to pi/4

What was the phase difference pi/8?
Yeah thats what I got

10.1? I did.

i got pi/4
7. anyone ran out of time? was a hard paper tho
8. I bet i can predict the future,
this is where your going to be next year

9. And the maximum emf I got 1462.5

i got .725 but i gave it as .7 as the 5N was 1 sigfig do you recon thats acceptable?
11. 35 for an A
12. (Original post by 456CJ)
And the maximum emf I got 1462.5
yeah i got around that but i think it depends on your graph
13. guys why did we choose physics
14. (Original post by mstrcvk)
Yeah thats what I got
It was 1/8 of a wavelength (2pi), so pi/4
15. (Original post by metrize)
35 for an A
if that's the case maybe I can scrape a C
16. (Original post by ilovepotc)
I got that
I got that eventually, did a bit of trial and error and then worked backwards to check the answer haha.
17. (Original post by metrize)
35 for an A
Wishful thinking, I reckon 48 for an A
18. (Original post by 456CJ)

Nahh I remember getting no answer for this one if I remember correctly
19. (Original post by Chickenslayer69)
Think you had to use lambda = h/mv. With an alpha particle, there are 4 protons/neutrons, so the equation turns into lambda = h/4mv, leading to 4lambda = h/mv.
Yeh I did 1/4 based on your logic as well. It's defo correct.
20. The paper is out of 69 or 70 still?
