_ states that electrical field strength is directly proportional to number of charges being separated and indirectly proportional to distance between them squared
coulomb’s law
This statement is known as Coulomb’s Law, which states that the magnitude of the electrical force between two charged objects is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb’s Law can be represented as:
F = kQ1Q2 / r^2
where F is the force between the two charges, Q1 and Q2 are the magnitudes of the charges, r is the distance between the charges, and k is Coulomb’s constant (a proportionality constant that relates the units of charge, distance, and force). Thus, the statement that electrical field strength is directly proportional to number of charges being separated and inversely proportional to distance between them squared is a concise way of summarizing Coulomb’s Law.
