3 cards from this section. Quick, good the night before a test.
Define electric flux.
Think about the flow of electric field lines.
What is a Gaussian surface?
It helps us visualize electric fields.
What does Gauss's Law relate?
Consider what Gauss's Law mathematically expresses.
The electric field inside a uniformly charged sphere is:
Think about charge distribution.
A charged sphere has a total charge of +5 μC and a radius of 0.1 m. Calculate the electric field at a point 0.15 m from the center.
What happens to the field outside a sphere?
Determine the electric field strength at a distance 2 m from an infinite charged plane with surface charge density σ = 2.5 μC/m².
Recall how electric fields behave with surface charge on an infinite plane.
