NEET Physics Coulomb's Law Assertion Reason Question
Assertion (A): Coulomb's law describes the force between two point charges as directly proportional to the product of their charges. | Reason (R): The proportionality constant k in Coulomb's law has a large value in SI units because the unit of charge (coulomb) is defined by the unit of current (ampere).
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
Coulomb's law states the force is proportional to the product of charges, and the large value of k is due to the definition of the coulomb via the ampere, as per the NCERT context.
