1.	Two conducting spheres of radii `r_(1)` and `r_(2)` having charges `Q_(1)` and `Q_(2)` respectively are connected to each other. There isA. no change in the energy of the systemB. an increase in the energy of the systemC. always a decrease in the energy of the systemD. a decrease in the energy of the system unless `Q_(1)r_(2)=Q_(2)r_(1)`
Answer» Correct Answer - D If potentials of two spheres are same i.e., `V_(1)=V_(2)implies(Q_(1))/(4piin_(0)r_(1))=(Q_(2))/(4piin_(0)r_(2))` `Q_(1)r_(2)=Q_(2)r_(1)` There will be no redistribution of charge and hence no loss of energy
