It's from an exam paper called NEST (National Entrance Screening Test) conducted in India. Its for the year 2016.Doc Al said:
Electrostatics is the study of electric charges at rest. It involves studying the behavior of electric charges and the electric fields they create.
An E-field, or electric field, is a region in which an electric charge experiences a force. It is a vector field that can be represented by electric field lines.
The E-field near 2 point charges can be calculated using Coulomb's Law, which states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The E-field between 2 point charges decreases as the distance between them increases. This is because the force between the charges decreases as the distance increases.
Studying the E-field near 2 point charges is important in understanding the behavior of electric charges and how they interact with each other. This knowledge is crucial in many applications such as designing electronic devices, understanding lightning strikes, and creating new technologies such as capacitors and batteries.
