NEET Physics Coulomb's Law Assertion Reason Question
Assertion (A): The electrostatic force between two charges remains unchanged if an identical but uncharged sphere touches each charge and the separation is halved. | Reason (R): When a charged sphere touches an identical uncharged sphere, the charge is redistributed equally on both spheres.
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
After touching, each sphere carries half of the original charge, and halving the separation maintains the force due to the inverse square law, as cited in the NCERT chunk.
