the silk will rub of the electrons on the silk, leaving the glass positively charged
The Physicist who said first that the charge on a glass rod rubbed with silk is positive was Michael Faraday.
Positive charge
Rubbing a plastic body like comb on dry hair can impart static charges on it. Also, glass rod rubbed on silk cloth, ebonite rod rubbed on silk cloth. Most of them we have learnt in our schools. If you want a something really huge, try Van de Graaff generator.
For example as glass rob is rubbed with silk then glass becomes positively charged and silk negatively charged. This is mainly because of the transfer of electrons right from glass to silk. But in case of ebonite rod rubbed with fur electrons get transferred from fur to ebonite. So ebonite becomes negatively charged and fur positive charged Now in case of an atom or molecule one or more electrons get removed and so that atom or molecules become a positive ion. Same way as electron gets attached with a neutral atom then it becomes negative ion.

it created an electrical charge
One is a negative static charge, the other positive. The exact charge depends on how long and how vigorous the rubbing is. teehee
you will get a static electric charge :)
Both are examples of static electricity generation. The big difference is the way the electricity is generated.
There is a very big difference between the electrical charge of a balloon rubbed in a person's hair and a glass rod rubbed with silk. The charge from the balloon will just make it stick to objects. The charge from the glass rod will emit a very large electrical shock that might knock a person to the ground. This is because the glass rod is a better conductor of electricity than the balloon.
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges
