    Was the effect the motor effect or electromagnetic induction?
    I think it was motor effect. The picture given corresponds to the common picture used for the motor effect and it did ask which effect.

    What was the reason for ditching the plumb pudding model for the 2 mark?
    I put because their results were not supported by the plumb pudding model so they had to modify the model to support the results they obtained.

    That's not correct; the greatest launch angle did not have the greatest range.
    I said as angle INCREASES, the range DECREASES. I didn't put what you just said?

    How would everyone rate P2 and P3 on difficulty between 1 and 10. I'd say 7 for P2 and 4 for P3
