AnswerIt really depends on what type you plug you are using. From your use of the word. 'earth' (rather than 'ground'), you may be referring to the plugs used in the UK, Ireland, and places like Malta, Cyprus, and the Gulf States? If so, then the earth pin is the longest of the three, and located at the top of the plug. Some European plugs don't use an earth pin at all -in Germany, for example, they use a pair of contacts located in the moulded recesses located on each side of the plug.

Is it okay to use an adapter to change a three pin plug into a two pin plug?
No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.

Why third pin is plastic in 3 pin plug?
Double-insulated electrical appliances, such as electric drills, only require two connections -a line and a neutral- to the supply. An earth (ground) connection is unnecessary. In the UK, all electric socket outlets have shutters that blank off the line and neutral terminals when there is no plug inserted. These shutters are operated by the earth pin of the plug. As double-insulated appliances don't require an earth connection, a plastic earth pin is moulded into the plug in order to open the socket shutters in place of a normal metallic earth pin.
