Chapter 4, Problem 4.10P

A sphere of radios a carries a surface density of pr0 C/m2. (a) Find the absolute potential at the sphere surface (b) A grounded connecting shell of radius b where b > a is now positioned around the charged sphere What is the potential at the inner sphere surface in this ease?

Hey I was wondering if you can help me with this problem plz   Figure shows a plastic rod with a uniform charge −Q. It is bent in a 120° circular arc of radius r and symmetrically placed across an x axis with the origin at the center of curvature P of the rod. In terms of Q and r, what is the electric field E ⃗ due to the rod at point P?
A total charge of Q is uniformly distributed in a noncunducting sphere with a radius of R. A point charge with a total charge of -Q  is at the center of the sphere.  A. Derive an equation for the electric feild strength where r<R (in other words find the electric field strength when you at a radius less that R). B. Make a diagram and show the gaussian surface that was used to derive the equation
2 very thin spherical shells are given as in the figure below. Let the loads with the inner shell load -Q and outer shell load + Q be uniformly distributed to these shells. What should be the electric field strength for the distance R inside the inner shell?
