    That moment when you write "the hydrogen ion has no charge".... hydrogen ION has no charge fml 😂
    yes it does, it's charge is +1 isn't it?

    I got 16.7% for the percentage charge decrease question.

    23.8m for the radius of the path of the bike.
    2.09ms^-1 for speed of bike.

    Some multiple choice answers I remember:

    1. Something to do with magnetic field causing circular motion
    Area under graph = change in momentum
    1/root(6)
    Half charge on one of particles
    Anti-up Down
    0.024N
    I got all the same answers as you! Apart from the % one. I got 66% and I think my radius was 22m

    What did you guys get for the radius of the bike? I got 20 point something meters, I feel as if this value is too large, but I'm unsure
    I got 20.4m.

    For Q11 wavelength i got 2.1×10-11 i think or ×10-something else.

    What did people get for the conservation of momentum question where you had to work out the velocity of the glider? Also was the collision elastic or in elastic?? Think I made a silly mistake typing it into my calculator . Thought on A* grade boundary???

    It was 20.4 for radius, but for the percentage it was to 2 sig figs 16.7 = 17%
