Answer: Electrons have been removed from the glass object in the rubbing process.
Because, in every atom proton and neutron remain in the nucleus , whereas electron are revolving around the nucleus . So , electron can be transfer more easily form one atom to the another as compared to proton . Electrons are mobile in nature . They can easily move .
So , postive charge on the glass develops due to removal of electrons from it .
Therefore, election from the glass object.
