This is probably a very basic to most of you physics people but It's frustrating me and I need to get answers ASAP.
Just saw an experiment on YouTube where they rub a silk on some sort of glass rod, and the rod becomes negatively charged. If you move it towards a positively charged balloon, the balloon will move towards the rod. This confuses me a lot. Positively charged means there are more protons than electrons, right? So when you move an negatively charged object, meaning more electrons, the electrons of the positively charged object will go to the other side away from the negatively charged object. I'm okay with that, but why does the protons (and the object) goes towards the side of the negatively charged object as seen on the visualizations, if protons doesn't actually move?
Please enlighten me.
