When it is connected by wire, all charge from inside is conducted to the outer shell.
And then potential inside the shell is a constant and equal to the potential at the surface i.e kQ/b
kQ/a = V So, Q = Va/K
So, New Potential = k(Va/k)/b = Va/b

Dear student,

Please find the answer to your question below.

When it is connected by wire, all charge from inside is conducted to the outer shell.

And then potential inside the shell is a constant and equal to the potential at the surface i.e kQ/b

kQ/a = V So, Q = Va/K

So, New Potential = k(Va/k)/b = Va/b

Hope it helps.

Thanks and regards,
