Question

Gauss's Law

Answer 1

What about it, can you please copy and past the question...please, or i can't help.

Answer 2

call me when you are ready..

Answer 3

What is the question

Answer 4

My goodness have some patience...You can obviously see my typing...
Find the electric field everywhere for a uniformly charged solid sphere that has a radius R and a total charge Q that is uniformly distributed throughout the volume of the sphere that has a charge density \[\rho=\frac QV\], where \[V=\frac 43 \pi R^3\] is the volume of the sphere.
It's an example in my book.

So far I understand that I need to make shell around the charged solid, and use that find the \[\phi_{net}\]
and then we would find the Charge because \[Q=\phi_{net}\epsilon_0\]
From that charge we find the electric field.....

Here is my question

What do they mean by
\[\textrm{For r}\ge R, Q_{inside}=Q\]
\[\textrm{For r}\le R, Q_{inside}=\rho V'\]

Answer 5

They mean that once your shell goes beyond the radius of the charged sphere, the amount of charge inside is constant (obviously, just the total charge of the sphere). But when you're inside, the charge inside your shell is less than that.

Answer 6

can you show me where exactly? I'm am a visual learner.

Answer 7

"....once your shell goes beyond the radius of the charged sphere, the amount of charge inside is constant..."
" But when you're inside, the charge inside your shell is less than that."
