AQA Physics B Unit 5 - How did you do?

Why?

The way to do that was to consider the horizontal and vertical components of the dust particle. Since It was in an electric field it experienced a horizontal force F=vq/d this force causes acceleration horizontally..so an acceleration is caused (f=ma)
since s=ut+0.5at^2
and the distance from dust particle to edge was 2m. You sub in 2for S
and the acceleration u got previously. This will give u time it takes for particle to reach edge (t). Since it is going up with a constant vertical velocity.. u say distance=speed X time. (basically, if the particle takes time to reach edge.. there must be an edge left when it gets there) therefore the distance travelled in the time it takes to get there has to equal minimum length of plates

2.1m approx

I thought york gave higher offers, something like ABB, but nevermind

good luck with chem

lol.. cant remember.. if u can remember how fast the dust particle was travelling vretically i cud prob work it out backwards

There's quite a lot of Physics Courses at York, and if I remember correctly, one course for straight Physics gives out higher offers than the other - Maybe because its a longer degree (4 year) or something.

I think one gives ABB or even AAB, whereas the other gives BBB.

One of my friends has a EE offer to do physics at Cambridge.

Im so proud of her!!!

Everybody loves her.lol

anyone got a copy of the paper then? i no some ppl have them from maths etc?

I might be able to get one tomorrow, Ill speak to my Physics teacher after my chem exams..

Is it me or does 58/100 to get an A seem very low? I'm sure I had a look on AQA mark boundaries etc and it was usually much higher to get an A.

Guess last year's and this year's were hard?

Thats an easy paper apparantly, I think January this year(or last) You only need 52/100 to get an A. I think this years paper will be about 55 for an A..

OK, good luck.
