Final answer:
The volume density of charge is the amount of charge per unit volume. The equation to calculate it is ρ = Q/V. Near negative particles, there is an excess of negative charge, while near positive particles, there is an excess of positive charge.
Step-by-step explanation:
The volume density of charge refers to the amount of charge per unit volume.
The equation to calculate the volume density of charge is given by:
Volume Density of Charge (ρ) = Q/V
Where ρ is the volume density of charge, Q is the total charge, and V is the volume.
When considering negative and positive particles, negative particles have an excess of electrons and positive particles have a deficit of electrons. Near negative particles, there will be an excess of negative charge, while near positive particles, there will be an excess of positive charge.
