Question

Two insulated charged spheres of radii $R_{1}$and $R_{2}$ having charges $q_{1}andq_{2}$ are respectively connected to each other. The there is.

• A. An increase in energy of the system
• B. No change in energy of the system
• C. Always decrease in energy
• D. A decrease in energy of the system unless $q_{1}R_{2} = q_{2}R_{1}$

Answer 1

Answer: (D)

A decrease in energy of the system unless

$q_{1}R_{2} = q_{2}R_{1}$

Answer 2

: In redistribution of charge there is always loss of energy, unless their potentials are same or

$q_{1}R_{2} = q_{2}R_{1}$
