In a vacuum, two particles have charges of $q_{1}$ and $q_{2}$, where $q_{1}=$ $+3.5 \mu \mathrm{C} .$ They are separated by a distance of $0.26 \mathrm{m},$ and particle 1 experiences an attractive force of $3.4 \mathrm{N} .$ What is $q_{2}$ (magnitude and $\operatorname{sign}$ )?

Key Concepts

Coulomb's Law

This law describes the interaction between two point charges. It states that the magnitude of the electric force between two charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. In mathematical terms, F = k|q1*q2|/r², where k is Coulomb's constant.

Electric Charge

Electric charge is a fundamental property of matter that determines how particles interact with each other. Charges can be positive or negative, and the interaction between charges is defined by their magnitudes and signs. The sign of a charge plays a crucial role in determining whether the force between charges is attractive or repulsive.

Electrostatic Force

The electrostatic force is the force between two charged objects. It is a non-contact force that can either attract or repel depending on the signs of the charges involved. The calculation of this force in a vacuum is straightforward using Coulomb's Law, without the need to account for medium-related corrections.

Inverse Square Law

The inverse square law in physics states that a specified physical quantity is inversely proportional to the square of the distance from its source. In the context of electrostatics, it explains how the force between two charges decreases as the distance between them increases.

Sign Conventions in Electrostatics

The sign of electric charges determines the nature of the force between them. Charges with opposite signs attract each other, while charges with the same sign repel. This concept is essential when using Coulomb's Law to not only calculate the magnitude of the force but also to predict whether the interaction is attractive or repulsive.
