Gauss' Law: Conductor, Insulator, Electric Field

[JoeyGoh]

Homework Statement

UNDONE

Relevant Equations

Charge or Electric Field Perhaps, Gauss's Law

I'VE SEEN MANY QUESTION WROTE C/m, WHAT IS C? CURRENT?
Consider an insulating sphere with 10μC of charge uniformly distributed through its volume. The sphere is surrounded by a conducting spherical shell that has a total charge of −3μC. Outside the conucting shell is an insulating shell with total charge 20μC uniformly distributed through its volume. In the figure below, which shows a cross section of the structure, the darker shaded regions are insulators and the lighter shaded region is the conductor. Description of the image: The center wrote as 10mikroC with darker shaded. The outer circle wrote as -3mikroC with lighter shaded. There's a space between 10mikroC and -3mikroC that labeled as A. The biggest circle surrounded the rest wrote as 20mikroC which also have darker shaded.

WHAT IS NEEDED TO BE CALULATED??? THE AREA "A"???

C is coulombs which is a unit of charge.

A is just the region between the first sphere and the first spherical shell.

With that said, I don’t even see a question.

I would think they would be asking to “find the field in all regions”

Without specifying the relevant radii?

Without specifying the relevant radii?

Okay that’s true. I honestly have no idea what the question is asking.

 

[kuruman]

Okay that’s true. I honestly have no idea what the question is asking.

The only question that can be answered numerically on the basis of what is given is
"What is the total charge on the inner and outer surface of the conducting shell?"

I would agree. But I wish we didn’t have to guess what the question is lol.

Me too.
