    Can anyone explain these 2 questions to me?

    Posted from TSR Mobile
    I have not done the first one yet but the second one is F=ma=mdv/dt= d(mv)/dt
    So the gradient of the line!

    Does anyone know of any places to get a load of difficult unit 4 questions?

    I found this custom made unit 4 paper on TSR but it doesn't have a mark scheme- would greatly appreciate it if someone made one though!!

    The magnetic field is into the page. Using the left hand rule, I figured that D was negatively charged.

    BUT the book says that C is negative, meaning D is positive. I dont understand..

    I have the same revision guide and I got D is negative as well so you're not going mad. Must be an error in the book.. Noticed a couple of small errors in it actually, which really isn't helpful.

    Thanks. It's a bit annoying that they were really vague with the dimensions of the square because all they said was "the sides".

    Looking at the question I agree with you two.

    Oh okay. Yeah I'm still not that good haha, but getting better (y)
    What do you get wrong with the capacitors questions? It's always saying what happens when charging, or what happens when discharging and then doing a RC calculation to work out if the capacitor will be sufficient (which it always is) haha

    I am just so off with some the questions. I get charging and discharging but dont understand some of the longer written questions. The calculations are easy though.
