Question

sep develop and use models draw a model of the force between two negatively charged particles. include in your model how the force changes if the charge of the particles change or if the distance between the particles change.

Explanation:

Step1: Recall Coulomb's law

The force between two charged particles is given by $F = k\frac{q_1q_2}{r^{2}}$, where $k$ is Coulomb's constant, $q_1$ and $q_2$ are the charges of the two particles, and $r$ is the distance between them.

Step2: Analyze charge - force relationship

If the charges $q_1$ and $q_2$ increase (while $r$ is constant), the magnitude of the force $F$ increases. Since the particles are both negatively - charged, the force is repulsive.

Step3: Analyze distance - force relationship

If the distance $r$ between the two negatively - charged particles increases (while $q_1$ and $q_2$ are constant), the magnitude of the force $F$ decreases according to the inverse - square law.

Step4: Model drawing

Draw two negatively - charged particles (represented by minus signs). Draw arrows pointing away from each other to represent the repulsive force. You can add labels to show that increasing the charges makes the arrows (force) longer, and increasing the distance between the particles makes the arrows (force) shorter.

Answer:

Draw two negatively - charged particles with repulsive force arrows between them. Indicate that increasing charge increases force magnitude and increasing distance decreases force magnitude.
