Understanding the Basics of Electrostatics

Electrostatics is a branch of physics that deals with the study of electric charges and their interactions. When two charged particles are brought close to each other, they experience an electrostatic force. This force can be attractive or repulsive, depending on the nature of the charges. In this article, we will explore the concept of electrostatic force and calculate the electrical force between two charged particles.

The Coulomb's Law

The electrostatic force between two charged particles is described by Coulomb's Law, which states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as:

F = k \frac{q_1 q_2}{r^2}

where:

$F$ is the electrostatic force between the two charges
$k$ is Coulomb's constant, which is equal to $8.99 \times 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2}$
$q_1$ and $q_2$ are the magnitudes of the two charges
$r$ is the distance between the two charges

Given Values

We are given the following values:

$q_1 = +6 \, \text{C}$
$q_2 = -4 \, \text{C}$
$k = 8.99 \times 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2}$

Calculating the Electrical Force

To calculate the electrical force between the two charged particles, we can plug in the given values into the equation for Coulomb's Law:

F = k \frac{q_1 q_2}{r^2}

Since we are not given the distance between the two charges, we will assume a value of $r = 1 \, \text{m}$ for the purpose of this calculation.

F = (8.99 \times 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2}) \frac{(6 \, \text{C}) (-4 \, \text{C})}{(1 \, \text{m})^2}

F = (8.99 \times 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2}) (-24 \, \text{C}^2)

F = -2.16 \times 10^{11} \, \text{N}

Conclusion

Applications of Electrostatics

Electrostatics has numerous applications in various fields, including:

Relativistic Effects: Coulomb's Law does not take into account relativistic effects, such as the behavior of charged particles at high speeds.
Non-Linear Effects: Coulomb's Law assumes a linear relationship between the force and the distance between the charges, which is not always the case in reality.

Conclusion

In conclusion, the electrical force between two charged particles is described by Coulomb's Law, which states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. We calculated the electrical force between two charged particles with magnitudes of $+6 \, \text{C}$ and $-4 \, \text{C}$ , assuming a distance of $1 \, \text{m}$ between them. The result was a force of $-2.16 \times 10^{11} \, \text{N}$ . Electrostatics has numerous applications in various fields, including electric motors, particle accelerators, semiconductor devices, and power transmission.
