Question restatement: In the Coulomb’s Law formula, what do the symbols F, q, and r, mean respectively?

Option a: 'Charge, force, distance between the charges.' This assigns charge to F, which is incorrect because F represents the force; charge is represented by q. The misassignment here confuses the roles of the variables.

Option b: 'Free-fall acceleration, quantity, radius of the charges.' This option introduces terms that have no relation to Coulomb’s Law: free-fall acceleration is not a symbol in this law, and radius is not the variable used for r in Coulomb’s Law. Overall, this is irrelevant and inaccurate.

Option c: 'Force, charge, distance between the charges.' This matches the standard definitions in Coulomb’s Law: F denotes the electrostatic force between charges, q denotes the electric charge, and r denotes the distance separating the charges. This option correctly aligns with the conventional notation used in the law F = k * |q1 q2| / r^2, where F is the force, q1 and q2 are charges, and r is their separation distance.

Option d: 'Field, quality, rotational speed of the charges.' This option introduces 'field' and 'quality' which do not correspond to F and q in Coulomb’s Law, and 'rotational speed' has no place in the basic Coulomb framework. It conflates concepts from fields and dynamics incorrectly.

Additional notes: The Coulomb’s Law describes the magnitude of the electrostatic force between two point charges. F depends on the product of the charges q1 and q2, inversely on the square of the distance r between them, and is directed along the line joining the charges. The standard symbols used are F for force, q for charge, and r for the separation distance, which is exactly what option c states.
