Question

conservation of charge ?state and explain superposition principal​

Answer 1

The principle of superposition of forces in electrostatics states that when a number of charges are interacting, the electrostatic force between two charges is not affected by the existence of the other charges and the total electrostatic force on a charge is the vector sum of all the forces due to other charges.

Answer 2

Answer:

conservation of charge ?

The law of conservation of charge states that electric charge can neither be created nor destroyed. In a closed system, the amount of charge remains the same. When something changes its charge it doesn't create charge but transfers it.

state and explain superposition principal​

“The principle of superposition states that every charge in space creates an electric field at point independent of the presence of other charges in that medium. The resultant electric field is a vector sum of the electric field due to individual charges.”

let us consider one positive charge, and two negative charges exerting a force on it, from the superposition theorem we know that the resultant force is the vector sum of all the forces acting on the body, therefore the force Fr , the resultant force can be given as follows,

Fr−→ = 14π∈[Qq1r212r^12 + Qq2r213r^13]
