Electrostatics is the branch of physics that studies the phenomena and properties of stationary or slow-moving electric charges.
An electrostatics problem is a mathematical question that involves the study of electric charges at rest, their interactions and the resulting electric fields.
Some common examples of electrostatics problems include calculating the electric field generated by a point charge, determining the force between two electric charges, and finding the potential difference between two points in an electric field.
The most commonly used equations in electrostatics problems are Coulomb's law, Gauss's law, and the equations for electric potential and electric field.
Electrostatics has many real-life applications, such as in electrostatic precipitators used to remove pollutants from industrial emissions, in printers and photocopiers to transfer toner onto paper, and in particle accelerators used in research and medical treatments.
