Explain how rubbin fur on an ebonite rod produces a charge on the rod. What chrage is produced in the rod?

I understand the question, but how am I to know if it will have a positive or negative charge? Also, I don't quite understand how you charge something electrically by rubbing i, so I would really appreciate an explanation. Thank you! :-)
