- Homework Statement
- An infinite planar "slab" of charge sits in the x-y plane. It has a thickness of 10cm and a volume charge density ρ=0.005z^2, where the constant 0.005 has units C/m^5 and z=0 is the center of the slab. What is the electric field magnitude in N/C at z=2cm, inside the slab?
- Relevant Equations
- $$\oint_{}^{} E \cdot dA = \frac {q_e}{\epsilon_o}$$
Draw a Gaussian pill box that starts from 0 (half way between the slab) and extends towards 2 cm.$$A \times \int_{0}^{0.02} \rho dz$$
I'm not sure if I should multiply the integral by A (area) or V (volume)
And if area would I multiply by 0.02^2?
I'm confused here. Thanks for your help.
