Two thin conducting shells of radii R and 3R are shown in the figure. The outer shell carries a charge +Q and the inner shell is neutral. The inner shell is earthed with the help of a switch S.
  • a)
    With the switch S open, the potential of the inner sphere is equal to that of the outer
  • b)
    When the switch S is closed, the potential of the inner sphere becomes zero
  • c)
    With the switch S closed, the charge attained by the inner sphere is _q/3
  • d)
    By closing the switch the capacitance of the system increases
Correct answer is option 'A,B,C,D'. Can you explain this answer?
Verified Answer
Two thin conducting shells of radii R and 3R are shown in the figure. ...
(A)  Potential of inner shell is due to potential developed by outer shell.
(B)  Since the inner shell is Earthed so its potential becomes zero.
(C)  Vinner=(KQ/3R)+(KQI/R)=0⇒rQ'=−Q/3

(D)  It capacitance becomes =4π∈0R1R2/R2−R1+4π∈R2
Therefore the correct answer is option A B C D.
