for questions 1 and 2: set charge 1 to -8 μc and charge 2 to +8 μc. 1. what do you observe about the…

Brief Explanations:

According to Coulomb's law, two charged particles with opposite - signs attract each other and there is an electrostatic force between them. The magnitude of the electrostatic force between two point - charges $q_1$ and $q_2$ separated by a distance $r$ is given by $F = k\frac{\vert q_1q_2\vert}{r^2}$, where $k = 9\times10^{9}\ N\cdot m^{2}/C^{2}$. Since the charges are non - zero ($q_1=- 8\ \mu C=-8\times10^{-6}\ C$ and $q_2 = 8\ \mu C = 8\times10^{-6}\ C$), there is a non - zero force between them. Without knowing the distance $r$, we can't calculate the exact force value, but we know there is a force.

Answer:

None of the provided options can be determined as correct without knowing the distance between the charges.
