Gauss's Law Flashcards
1
Q
What is Gauss’s Law?
A
◯∫∫E⋅dS=Qencl/ϵ0
Where Qencl is the total charge enclosed
E is the electric field
S is the surface normal vector
ϵ0 is the permittivity of free space
2
Q
For what surfaces is Gauss’s law true for?
A
All closed surfaces with the choice of surface called a Gaussian surface
3
Q
When is the electric field radially outwards?
A
When the charge is greater than zero
