In the above question, if plates P_1 and P_2 are connected by a thin conducting wire, then the amount of heat produced will be

Answer»

`Q^2/(Aepsilon_0)d`
`(5Q^2)/(Aepsilon_0)d`
`(2Q^2)/(Aepsilon_0)d`
none of these

SOLUTION :FINAL charges are as shown, Energy stored in the capacitor will be zero FINALLY.
Heat produced `=DeltaH=U_(1)-U_(1)=(1)/(2)(Q^(2))/(epsilon_(0)A//d)-0`
