Two conducting spheres of radii r(1) and...

Two conducting spheres of radii `r_(1)` and `r_(2)` having charges `Q_(1)` and `Q_(2)` respectively are connected to each other. There is

A

No change in the energy of the system

B

An increase in the energy of the system

C

Always a decrease in the energy of the system

D

A decrease in the energy of the system unless `Q_1R_2 =Q_2R_1`

Text Solution

Verified by Experts

The correct Answer is:
D
Initially potential is different.
When `Q_1/R_1 ne Q_2/R_2` current will flow in connecting wire, so that energy decreases in form of heat through the connecting wire.
Initially potential is different, hence current will flow.
