    Please help How to find the potential difference of a spherical shell

    I can frankly say I'm totally confused on how to solve this problem. Here it is: A think spherical shell of charge Q and uniform volume charge density p is bounded by radii r1 and r1 where r2>r1. WIth V=0 at infinity find the electric potential V as a function of the distance from the centre...

    Conducting sphere in a conducting spherical shell

    A conducting sphere that carries a total charge of 6 micro C is placed at the center of a conducting spherical shell that also carries a total charge of 6 micro C . (a) Determine the charge on the inner surface of the shell. (b) Determine the total charge on the outer surface of the shell...

    Graduate Rotational inertia of a THICK spherical shell

    Someone please tell me is I am doing this problem correctly.If I have a thick spherical shell with inner radius r, outer radius R, and mass M, I am getting [(2/5)M/(R^3-r^3)](R^5-r^5). It is not the same thing as subtracting I of large sphere from I of smaller one, different than (2M(R^2-r^2)...

    Graduate How Do You Solve Inhomogeneous PDEs with Homogeneous Boundary Conditions?

    I have a problem on my homework that is really confusing. I need to solve the partial differential equation in a spherical shell with inner radius = a and outer radius=b: (Laplacian u)=1 in spherical coordinates. The boundary conditions are u=0 on the inner radius r=a, and du/dr=0 on outer...
