Firstly sorry for my english....
So I have a point charge Q inside uncharged hollow sphere and I am supposed to express E.
What I have come to:
If I say the charge will be Q- it should look as one the attached picture which means there will be non zero E outside the shell.
So outside shell it should be standard Q-/(4*pi*epsilon*r^2)
In the shell it will be E=0 because of free charges in conductors.
And inside shell there it will be same as on the outside.

Are my thoughts correct? Thanks for adice in forward...

Hi,

That sounds right to me but i'd have to refer to some reference to be sure as this kind of question only comes up once in a while
