A workshop sprays liquid glaze onto a ceramic ornament. Which arrangement of charges would make the glaze droplets spread apart and be attracted to the ornament?
The droplets are a mix of positive and negative; the ornament is positive.
All the droplets have the same sign of charge; the ornament has that sign too.
All the droplets have the same sign of charge; the ornament has the opposite sign.
The droplets are left uncharged; the ornament is given a large charge.
