Gauss's Law Flashcards
Lesson 4
this can be used as an alternative procedure for calculating electric fields
gauss’s law
it is an expression of the general relationship between the net electric flux through a closed surface and the charge enclosed by the surface
gauss’s law
coined the term gauss’s law
karl friedrich gauss
it is the product of the magnitude of the electric field and the surface area, A, perpendicular to the field
electric flux
where does the positive point charge located in a sphere?
at the center
true or flase: in a cube The field lines pass through two
surfaces perpendicularly and are parallel to the other four surfaces.
true
true or false: in closed surface, the net flux through the surface is inversely proportional to the net number of lines leaving the surface.
false
it is proportional
what is the other term for closed surface?
gaussian surface
true or false: The electric flux is proportional to the
number of electric field lines penetrating some surface.
true
field lines may make some angle θ with the perpendicular to the surface.
