SATHEE: Electrostatics Question 5

Electrostatics Question 5

Question: The insulated spheres of radii $R_{1}$ and $R_{2}$ having charges $Q_{1}$ and $Q_{2}$ respectively are connected to each other. There is [NCERT 1971, 84; MP PMT 2001]

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

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 $\frac{Q_{1}}{R_{1}} \neq \frac{Q_{2}}{R_{2}};$ current will flow in connecting wire so that energy decreases in the form of heat through the connecting wire.
