Assertion: When two charged spheres are connected to each other by a thin conducting wire, charge flow from bigger sphere to smaller sphere if initial charges on them are same.
Reason: Electrostatic potential enrgy will be lost in redistribution of charges.
Reason: Electrostatic potential enrgy will be lost in redistribution of charges.
View answer and explanation
Correct option: D
Assertion is false and Reason is true
Option D (Assertion is false and Reason is true) is correct because positive charge flows from higher potential to lower potential, meaning from the smaller sphere to the bigger sphere if they have the same initial charges, and electrostatic potential energy is indeed lost during charge redistribution.
