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 l experiences an allractive force of 3.4 $\mathrm{N}$ . What is $q_{2}$ (magnitude and sign)?

Key Concepts

Force Direction and Charge Interaction

The direction of the force between charged particles is determined by the signs of the charges. An attractive force occurs when the charges are of opposite signs, while a repulsive force results from like charges. Recognizing this relationship helps in inferring the sign of an unknown charge based on the observed interaction.

Coulomb's Law

Coulomb's Law describes the force between two point charges, stating that the magnitude of the force is directly proportional to the product of the absolute values of the charges and inversely proportional to the square of the distance between them. This fundamental principle in electromagnetism allows us to calculate the force experienced by electric charges when placed in a vacuum.

Electric Charge

Electric charge is a basic property of matter that leads to electromagnetic interactions. Charges are quantified in coulombs and can be either positive or negative, which determines whether the forces between them are attractive or repulsive. Understanding charge is essential for explaining a wide range of phenomena in physics.

Unit Conversion

In many physics problems, it is important to convert units to maintain consistency throughout calculations. For example, converting microcoulombs to coulombs ensures that all quantities are expressed in the standard SI units, allowing for accurate application of equations such as Coulomb's Law.
