Two conducting charged spheres X and Y having unequal charges are connected by the wire. Which of the following is true?

Charge is conserved Electrostatic energy is conserved Both the charge and electrostatic energy is conserved Neither of these is conserved

Charge is conserved

Let initial charges be : q and Q. The final charges become : (q+Q)/2 Calculate the initial and final Potential Energy which will not be the same. Hence, energy is NOT conserved.
