A glass object receives a positive charge by rubbing it with a silk cloth. In the rubbing process, have pro- tons been added to the object or have electrons been removed from it?

The electrons being removed from glass.

Explanation:

Given the glass object became positively charged by rubbing with a silk cloth.

The protons are present in the nucleus and are not free to move. While the electrons are free to move and roam between objects. So, when a glass is rubbed with a silk cloth, the electron leaves the glass object that will make a positive charge on the object.
