NEET Physics Coulomb's Law MCQ Question
Which of the following statements about Coulomb's Law is correct?
Coulomb's Law states that the force between two point charges is inversely proportional to the square of the distance between them.
The force described by Coulomb's Law is always attractive, regardless of the charges involved.
Coulomb's Law applies only to charges that are at rest and cannot be used for moving charges.
The value of the constant k in Coulomb's Law is equal to the charge of an electron.
Correct Answer
Detailed Explanation
Coulomb's Law describes the force between two point charges as inversely proportional to the square of the distance between them, as stated in the provided NCERT context. Option B is incorrect because the force can be either attractive or repulsive depending on the charge signs. Option C is misleading as Coulomb's Law is primarily concerned with static charges but does not rule out other conditions. Option D incorrectly states the constant k's definition.
