Hello everyone.
If a static charge is placed inside a metallic box, there is going to be an E field inside the box, zero in the layer between the inner and outer walls of the box, and a field E outside the box, as if the box was not there.
If the same charge inside the metal box is accelerated instead, the E field that it produces will be zero outside the volume of the box (assume a perfectly conducting walls perfect reflection).
Why?
What about Gauss law? How does it apply in the second case for a Gaussian surface that surrounds the box?
thanks
