When a charge of amount q is given to an isolated metal plate x of surface area a,its surface charge density becomes $`, when an isolated identical plate is brought to x , the surface charge density on x becomes $``. when y is earthed, the surface charge density becomes $```. answer is $`=q/2a, $`=$`` and $```=q/a.. how..?

When charge Q is given to X it gets equally divided on the two surfaces of X i.e s =Q/2A

If Y is not earthed then
When Y is brought close to X ,the charge induced on inner surface of Y will be equal and opposite to that of inner surface of X i.e -Q/2 and charge on outer surface of Y will be +Q/2 .

But Y is earthed in the given problem.Potential of Y will be zero
