Combined Field Due to Two Point Charges
If there are many source charges, each contributes to the electric field at every site in their area. The electric field at a point in space close to the source charges is the vector sum of the electric fields caused by each source charge. Assume that the set of source charges consists of two charged particles. The electric field vector resulting from the first charged particle plus the electric field vector resulting from the second charged particle equals the electric field at point P.
Determining the overall electric field at place P is a vector addition since the two electric field vectors that contribute to it are vectors.
Therefore, the electric field intensity at each point resulting from a system or group of charges is equal to the vector sum of the electric field intensities attributable to individual charges at the same site. The vector sum of electric field intensities is given by E=E1+E2+E3+..+En.
Electrostatics
Electrostatics is the study of electric charges that are fixed. It includes an study of the forces that exist between charges as defined by Coulomb’s Law. The following concepts are involved in electrostatics: Electric charge, electric field, and electrostatic force.
Electrostatic forces are non contact forces that can push or pull on items without coming into contact with them. A storm cloud’s internal accumulation of static electricity produces lightning.
In this article, we will study in detail about electrostatics, its related definitions, formulas and examples based on them.
