@ raveesh
what u need to understand is that ita c concept of earthing ,
now frst of all u need to know what is earthing –
an earthing system or grounding system is circuitry which connects parts of the electric circuit with the ground, thus defining the electric potential of the conductors relative to the Earth's conductive surface.
so, you are asking about a spherical conducter that is inside a conducting shell .
so, in that case , all the charge on the conducting shell will be went to earth , and no charge will be remain thjeir in the shell ,
but the conducter will remain unaffected .
AND KINDLY MENTION THE FULL PROBLEM , SO, THAT WE CAN HELP U ACCORDINGLY ..
