abb0t · Answer

Yes, I think so. I recognize uniform surface, but I am not sure if it is open or closed surface.

dan815 · Answer

of a cube* sry

dan815 · Answer

and yes i think they are assuming its a conductor , so closed

dan815 · Answer

so can you explain why it would be yes

abb0t · Answer

Then Yes, I believe you can use Gauss's law for thei given.

abb0t · Answer

I think they can explain better than me: http://hyperphysics.phy-astr.gsu.edu/hbase/electric/gaulaw.html

abb0t · Answer

I don't remember E&M too well.
