A conducting sphere of radius , carrying charge , lies inside an uncharged conducting shell of radius . If they are joined by a metal wire,
(A) amount of charge will flow from the sphere to the shell
(B) amount of charge will flow from the sphere to the shell
(C) amount of charge will flow from the sphere to the shell
(D) amount of heat will be produced
(A) amount of charge will flow from the sphere to the shell
(B) amount of charge will flow from the sphere to the shell
(C) amount of charge will flow from the sphere to the shell
(D) amount of heat will be produced
View answer and explanation
Correct option: C
and are correct
Option C (C and D are correct) is correct because when the spheres are connected, they reach the same potential, causing all the charge to flow to the outer sphere, and heat is generated due to the change in electrostatic energy.
