Explanation:

Opposite electric charges attract each other. When the glass attracts the paper, this occurs because the glass has acquired a charge (typically from friction, like rubbing), which induces an opposite charge in the neutral paper, leading to attraction. This means the effective interacting charges on the glass and paper are different.

Answer:

The glass and the paper have different charges.
