For explaining why the website was wrong about the electron path, did we only have to say that it would be deflected towards the positive plate rather than negative? or was there more to it. I was really confused cos I didnt think that would be worth 3 marks?

Should have had a circular path too, not a sharp bend

Also, the electron is not instantaneously deflected by the electric field as it shows for a large portion of the electron's path to be undeflected whilst in an electric field. Also, it shows linear motion, however it should curve out a parabolic path towards the positive plate.

*parabolic. Magnetic field is circular i think.

I dont remember integration in physics.

I integrated and derived the kinetic energy formula whivh gave me the right answer. Was the answer to question 20 40 degrees?

 

[Sarthakgarg]

I also wrote that the electron should start deflecting from the start of the electric field, not from the middle of it...

 

[andrewkordos]

That question 20 tho... Needed to use trig identity got 60 degrees in the end

incorrect it was 40

 

[Sarthakgarg]

I got 60 degrees..... like iforgotmyname

yeah should be parabolic i mean, i just said curved in the exam anyway so that would probably suffice

nah i got 60 too fam

nah i got 60 too fam

+1

Also the magnet question i used integration to show that it was curve shaped

 

[Crisium]

I used integration for more than one question LOL i got the answer but do i get marks

Uninstall file atar.exe

Someone sig this

 

[HecticLad]

what did you lads get for that einsten/planck mc? wording was absolute shit

 

[Sarthakgarg]

what did you lads get for that einsten/planck mc? wording was absolute shit

Which one????

 

[HecticLad]

Which one????

it was like a table and it said choose the correct contribution of einsten and planck to quantum theory or something

 

[Drsoccerball]

nah i got 60 too fam

You sure ? Alot of people got 40

 

[HecticLad]

You sure ? Alot of people got 40

idk maybe i mixed up the vertical and horizontal components

why is it a parabolic path rather than a linear?

I got 40 for q20, Tflight=2Tmax height so yeh

Constant (non-zero) acceleration in one direction and 0 acceleration in the perpendicular direction.
