It was a average paper ive seen better! No ****ing rutherford was pissed!

What should the answer be for the reason as to why no more charges are being packed in the two ends of the aeroplane in constant velocity etc?

That was confusing

Must admitted it was too but that means high grade boundaries and tougher mark scheme

im not sure about my ans, but i wrote there is no change in the rate of flux cutting since the velocity is constant so the induced emf wud also be the same

So that means no more charge is being packed up?
Was the question talking about charges being packed or no charge at all?

And how did you draw the lines in the graph?

I'm pretty sure the question referred to why no extra charge was being packed up. I wrote constant velocity so constant force and so on.

Guys what are your predictions for grade boundaries? What do you think A* (90%) will be?

the magnetic flux of earth links with the wings of the aeroplane. When aeroplane is travelling at a constant velocity, the rate of change of magnetic flux linking the wings of aeroplane is constant therefore no further e.m.f is induced and hence no extra charges are build.
