“Does earth get charged? if it’s then where these
charge goes.”
Answer: The net charge of earth as a whole (including the atmosphere) is approximately zero. But the surface of earth(the solid part) has a net negative charge and the air blanket surrounding it has almost equal amount of positive charge. Due to this there exists an average electric field of 100 V/m near Earth’s surface.
The charge on earth is distributed on its surface only.
