SATHEE: Electrostatics Question 790

Electrostatics Question 790

Question: 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

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:

[d] When $\frac{Q_{1}}{R_{1}} - \frac{Q_{2}}{R_{2}}$ ; current will flow ii connecting wire so that energy decreases in the form of head through the connecting wire
