Question
which object represents a negatively charged particle? which object represents a positively charged molecule? which object represents an uncharged molecule? which object will not move when in an electric field?
1. Which object represents a negatively charged particle?
Electric field lines for a negative charge point towards the charge. Object B has field lines pointing inwards, indicating a negative charge.
Electric field lines for a positive charge point away from the charge. Object A has field lines pointing outwards, indicating a positive charge.
An uncharged molecule has no electric field lines (since it has no net charge). Object C has no field lines, so it's uncharged.
