The electric field between two adjacent uniformly charged hemispheres

[greg_rack]

here is the situation

Hi guys,

I should illustrate the motion of an electron in both cases, but I cannot really understand how will the field be like in the gap between the two(filled) hemispheres(conductor and non).

Another thing is: for the conductive hemispheres, does it make any sense to speak of "uniform charge density"(as mentioned in the statement of the problem)? Since these are conductors, won't all the charge arrange itself on the surface, creating a neutral charge on the inside?

Is there a problem statement (other than 'here is the situation) ?
And is there a diffence between up and down (other than from gravity?) ?

Unfortunately not... that's an idea for an insight I got by talking to a professor, which presented me with this task.
I would like to come up with something, even by "interpreting" the situation to make it reasonable.

And is there a diffence between up and down (other than from gravity?) ?

What do you mean?

I meant 'difference' , sorry.
Explanation: physicists always look for symmetries.

Okay, in that case, no;
up and down hemispheres are the same

Then there is no preference for either up or down...
