NEET Physics Coulomb's Law MCQ Question
Consider the following statements about Coulomb's Law: 1. The force between two charges is attractive if they are of opposite signs. 2. The electrostatic force depends on the distance between the charges according to the inverse square law. 3. The value of the proportionality constant k in Coulomb's law is arbitrary in SI units. 4. The total force on a charge due to multiple other charges is the vector sum of individual forces. Which combination of these statements is correct?
1, 2, and 4 only
2 and 3 only
1 and 3 only
1, 2, 3, and 4
Correct Answer
Detailed Explanation
Statements 1, 2, and 4 are correct as they accurately reflect the nature of electric forces as described by Coulomb's Law. Statement 3 is incorrect because k is not arbitrary in SI units, where it is approximately 9 × 10^9 N m² C⁻².
