Final answer:
If an object is lower on the electrostatic chart, it means that the object has a lower net charge compared to other objects on the chart. Negatively charged objects have an excess of electrons, while positively charged objects have a depletion of electrons.
Step-by-step explanation:
In the context of the electrostatic chart, if an object is lower on the chart, it means that the object has a lower net charge compared to other objects on the chart. Negatively charged objects have an excess of electrons, while positively charged objects have a depletion of electrons. The law of conservation of charge states that the net charge of a closed system is constant, meaning that charges can be transferred between objects, but the total charge remains the same.
