Answer Posted / sgk
Purpose of more diameter: So that the area of contact is
more and resistance offered is less and more current can
flow through it in case of fault without overheating.
Purpose of more length: So that the earth pin makes the
first contact with the supply before any other pin ensuring
safety of the personnel.
