Final answer:
To calculate the net electrostatic force on particle B due to the other two charges A and C, Coulomb's Law would be used, factoring in the magnitudes of the charges and the distances between them. Without distance information, a numerical value cannot be provided, but the method involves calculating each force separately and then finding the vector sum.
Step-by-step explanation:
The subject of this question is Physics, and it pertains to high school level (or potentially college level) given the content of electrostatics and Coulomb's Law. To calculate the net electrostatic force on particle B due to the other two charges, A and C, we will use Coulomb's Law which states that the force between two point charges is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them.
To solve this problem, we would need more information about the distances between the charges. However, the concept can be explained. If we knew the distances between B and each of the other particles (A and C), we could calculate the force exerted on B by A and B by C separately using the formula F = k * |q1 * q2| / r^2, where F is the force, k is Coulomb's constant (8.9875×10^9 N·m^2/C^2), q1 and q2 are the charges, and r is the distance between the charges. The net force on B would then be the vector sum of these two forces, taking into account their directions (attraction or repulsion).
