    Electromagnetism question: Current flowing between concentric spheres

    intuitively, it will be the same as discharging a regular capacitor through a resistor. However, instead of discharging to zero, it will discharge until both plates have equal and opposite charge? (Where this charge is q/2). Am I correct in saying this

    Electromagnetism question: Current flowing between concentric spheres

    I know that my solution is time dependant, and I initially tried to use a capacitor model of sorts, but I realised as it was filled with a conductive medium, I cannot use a capacitor model. So now I am very stuck on this

    Understanding First Order ODEs and Intersection of Curves

    I'm aware that I can introduce the perimeter p = dy/dx then I can rearrange my equation to make y the subject, then I can show that dp/dx = p/x. However, this only gives me a bunch of quadratic curves for my solution. However given part b I see that two curves are meant to intersect each point...
