Final Answer:
The relationship between distance from charges and electric field strength can be modeled using Coulomb's Law, E = k * Q / r², where E represents the electric field strength, k is Coulomb's constant, Q denotes the charge, and r signifies the distance from the charge.
Step-by-step explanation:
The electric field strength generated by charges is governed by Coulomb's Law, a fundamental principle in electromagnetism.
This law quantifies the relationship between the magnitude of charges and the distance between them. It is expressed mathematically as E = k * Q / r², where E represents the electric field strength.
In this equation, 'k' stands for Coulomb's constant, a universal constant approximately equal to 8.9875 × 10^9 Nm²C². 'Q' denotes the magnitude of the charge generating the electric field, and 'r' signifies the distance from the charge. Importantly, the electric field strength diminishes as the square of the distance ('r') increases.
Therefore, the further away an object is from the source charge, the weaker the electric field it experiences.
Understanding this relationship is pivotal in various fields, from physics to electrical engineering. It explains how the force between charges changes concerning their distance and helps in designing systems involving electric fields, like capacitors and circuits.
