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

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

i got .725 but i gave it as .7 as the 5N was 1 sigfig do you recon thats acceptable?

Yeah thats what I got
It was 1/8 of a wavelength (2pi), so pi/4

I got that
I got that eventually, did a bit of trial and error and then worked backwards to check the answer haha.

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.
