How can we help you if you don't tell us your hypothesis and why you think it is correct?

First and foremost is answer the questions and ask for comments on your answers. Do the work and people will be happy to direct you in the right direction.

My hypothesis is that
if wool is rubbed with plastic then the distance will increase because it has a weaker hold on electrons
