Electrostatics Question 790
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
Options:
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 when energy is transferred to the surroundings
D) a decrease in the energy of the system unless $ Q _{1}R _{2}=Q _{2}R _{1} $
Show Answer
Answer:
Correct Answer: D
Solution:
When$ \frac{Q _{1}}{R _{1}}-\frac{Q _{2}}{R _{2}} $ ; current will flow in connecting wire so that energy decreases in the form of heat through the connecting wire
