1. ### Using Gauss's law to determine elctric fields (Calculus based problem)

Ok the Gaussian surface would be a small sphere inside a different sphere. I know where +Q and -Q and i know how to find the \sigma and all of that stuff. I know to start with q'=(r^3/R^3)*q and integrate that from 0 to 2pi and i think the 2 radius or something from there. I know coulombs law...
2. ### Using Gauss's law to determine elctric fields (Calculus based problem)

Ok like I know the formula I have a good picture draw but not sure how to tackle this problem.... And by the way the idea of looking in the textbook to get started would be great if there was a textbook... Feel free to recommend one because I'm on my own with that
3. ### Using Gauss's law to determine elctric fields (Calculus based problem)

Homework Statement A sphere of radius R has a total charge +Q, uniformly distributed throughout its volume. It is surrounded by a thick spherical shell of inner radius R and outer radius 2R carrying a total charge -Q, also uniformly distributed throughout its volume. Using Gauss's law...
4. ### Electric field question

ok so I understand that for intergrating the 2 rods you set them up as \int dE1x+dE2x and the same for the y component but I am kinda stuck on what is next.

6. ### Electric field question

This is one question that I am not that sure how to get started with.
7. ### Electric field question

Homework Statement A thin, semi-infinite rod with a uniform linear charge density (lambda) (in units of C/m) lies along the positive x axis from x = 0 to x = 1; a similar rod lies along the positive y axis from y = 0 to y = 1. Calculate the electric field at a point in the x-y plane in the...
