Explanation / Answer
if electron goes from fur to rod ... fur is positively charged
else if electron goes from rod to fur ... fur is negatively charged
By rubbing the glass rod, you have caused electrons (which are negatively charged) to get stripped off the atoms in the rod, leaving it with a net positive charge. The extra electrons are picked up by the silk, giving it a negative charge.
