ughhh hate the smart tutoring kids that r like raw mark 90 is bad as if it won't scale up to a high band 6 :rolleyes: i'm literally struggling to even get a scaled mark 70

Bruh what did y'all think about the 1st quarks problem? I left it and came back later but still couldn't solve it. Also the question where you had to connect wires to rods to make an uneven current wtf was that

i was a bit confused but i answered it like with each pion and what were the two quarks idk if thats right tho

me too literally got the first one part of that question and then could not do the rest lmao. the wording was so weird
we had to use trigonometry to calculate angle of velocity at the end of uniform field then we could get the distance

What I didn't use trig. What I did for c was I found the time that it took to travel the horizontal distance because the parallel plates didn't accelerate horizontally only vertically so I could use he given speed u. Then I used the new vertical velocity after the plates which I found with the acceleration from a with v=u +at and multiplied that by the time taken to travel the rest of the distance. Also I'm pretty sure that I was supposed to add the displacement from b but I forgot fml. Anyways how did you use trig????

For that question you had to find the new vertical velocity using data from Part B and find the angle of the resultant velocity using the horizontal 2x10^6 m/s from the question

Then use that angle with the 0.03m also from the question to find the vertical distance using trig

And then you had to add on the 8.1mm they asked you to prove in Part B

I still think it should've been worth 4 marks

In the question they said that a pion was a meson AND that mesons are composed of two quarks

So you then looked at the table and added the charges of the correct quark and antiquark until they made sense
So ur prolly right

Maybe I'm remembering the question wrong but why can't you just separate the resultant velocity into horizontal and vertical components, find the time taken to travel the horizontal distance, then find out how much the electron travelled vertically with the new vertical velocity within that time and add the displacement from b? Wouldn't it be more trouble to do this with trig because they didn't give the whole velocity?

we didnt need the value of velocity, we just needed the angle. Ur way works too i think
