Salt crystal Four ions $\left(\mathrm{Na}^{+}, \mathrm{Cl}^{-}, \mathrm{Na}^{+},\right.$ and $\left.\mathrm{Cl}^{-}\right)$ in a row are each separated from their nearest neighbor by $3.0 \times 10^{-10} \mathrm{m} .$ The charge of a sodium ion is $+e$ and that of a chlorine ion is $-e .$ Determine the electric force exerted on the chlorine ion at the right end of the row due to the other three ions.

Key Concepts

Coulomb's Law

This fundamental law of electrostatics quantifies the force between two point charges. It states that the magnitude of the electric force is directly proportional to the product of the magnitudes of the two charges and inversely proportional to the square of the distance between them. This law is critical in calculating forces in systems of charged particles.

Electric Charge

Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. Charges can be positive or negative, and the interactions between different charges lead to attractive or repulsive forces. Understanding charge is essential in analyzing interactions within ionic compounds.

Electric Force

The electric force is the interaction between charged particles, resulting from their electric charge. It can be either attractive or repulsive depending on the signs of the charges. In problems involving multiple charges, the net electric force on any given charge is determined by the vector sum of the individual forces exerted by all other charges.

Superposition Principle

This principle states that the total electric force on a charge due to a collection of other charges is the vector sum of the forces exerted by each of these charges independently. It allows for the analysis of complex charge configurations by breaking them down into simpler pairwise interactions.
