Homework Statement
A certain region of space bounded by an imaginary closed surface contains no charge.
Is the electric field always zero on the surface? If not, under what circumstances is it zero on the surface?
Homework Equations
Φ = Qenclosed÷εo = EA
The Attempt at a Solution
Since the imaginary surface need no any material object. I think the E refres to the inside surface, so it is not zero...
