y earth pin is thicker & longer than live & neutral pin?

Expert Answer:
Dear student,
It is thicker because in order for it to protect people from high voltages the current path to earth has to have a lower resistance than the path from the high voltage supply. A thicker wire has a lower resistance.
Hope this helps.
