Main Question or Discussion Point

Hi I was just wondering what the answer to the following question would be:

If you bring a positively charged rod to an uncharged electroscope causing the vanes or leaves inside to diverge, are negative charges attracted to the knob of the electroscope or do positive charges repel to the vanes of the electroscope? I think it's the latter, but not sure why it also couldn't be the first.

In the electroscope, which is a solid conductor, only the negative charges (electrons) are free to move. The positive charges (protons in the metal atoms) are fixed in a lattice structure (the metal atoms are not free to move).
