Question
Which of the following is correct about Coulomb's law?
I. The bodies were small compared to the distance between them.
II. The force, F (of attraction or repulsion) was directly proportional to product of the two charges, and inversely proportional to the square of distance between them
III. The bodies were appreciably large compared to the distance between the bodies.

III. The bodies were appreciably large compared to the distance between the bodies.
Correct Answer
Option A is the correct answer.
Detailed Explanation
Coulomb's law applies to point charges, meaning the size of the charged bodies must be small compared to the distance between them (Statement I is correct, III is incorrect). It also states that the force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them (Statement II is correct).
Hint
Consider the conditions under which Coulomb's Law is valid and its mathematical formulation.
