Question
Which of the following is correct about Coulomb's law? I. The bodies were small compared to the distance between them II. Force is directly proportional to the product of charges and inversely proportional to the square of distance III. The bodies were appreciably large compared to the distance between them
Correct Answer
Option A is the correct answer.
Detailed Explanation
Coulomb's law strictly applies to POINT charges - i.e. bodies small compared to the separation (I is a valid assumption), and the force law itself is stated in II. III contradicts the point-charge assumption, so it is false. Answer: I and II only.
Hint
Coulomb's law strictly applies to POINT charges - i.e.
