Question

define the continuous distribution of charges explain F force that acts on test charge due to linear surface and volume distribution​

Answer 1

Answer:

With the help of Coulomb’s Law and Superposition Principle, we can easily find out the electric field due to the system of charges or discrete system of charges. The word discrete means every charge is different and has the existence of its own. Suppose, a system of charges having charges as q1, q2, q3……. up to qn.

• We can easily find out the net charge by adding charges algebraically and net electric field by using the principle of superposition.
• This is because:Discrete system of charges is easier to solveDiscrete system of charges do not involve calculus in calculations

A system in which charge is distributed over a conductor, is called continuous charge distribution system

But how to calculate electrostatics terms in continuous charge system? For an Example if there is a rod with charge q, uniformly distributed over it and we wish to find the electric field at some distance ‘r’ due it. It would be illogical and irrelevant to simply add electric field using principle of superposition as the charge is uniformly distributed over the rod. So we take a small element of the rod and integrate it with proper limits.

We consider element, based on how density of charge is centered on the material or object. If the charge is uniformly distributed over the surface of the conductor, then it is called Surface Density. If the charge varies linearly along the length of the conductor, then it is called Linear Charge Density. And if the charge changes with volume of the conductor, then it is called Volume Charge Density.
