Consider two neutral concentric conducting thin spherical shells of radii r and 3r. A particle of positive charge Q is fixed at a distance 2r from the common center of the shells. The inner shell can be electrically grounded through a resistance R2 with the help of another switch S2 as shown.H1 (Total heat) is dissipated in the resistance R1 after the switch S1 is closed keeping the switch S2 open until a steady state is reached: When steady state is reached after closing the switch S1,the other switch S2 is closed. Total Heat dissipated after the switch S2 is closed until a new steady state is reached is H2.(Take Q2πε0r=108 SI units)

Consider two neutral concentric conducting thin spherical shells of radii r and 3r. A particle of positive charge Q is fixed at a distance 2r from the common center of the shells. The inner shell can be electrically grounded through a resistance R₂ with the help of another switch S₂ as shown.
H₁ (Total heat) is dissipated in the resistance R₁ after the switch S₁ is closed keeping the switch S₂open until a steady state is reached:

When steady state is reached after closing the switch S₁,the other switch S₂ is closed. Total Heat dissipated after the switch S₂ is closed until a new steady state is reached is H₂.
