hi frnds...
first of all the charge inside any metal body is zero.
(.remember ur basic class lessons.)so when the man touch
the +ve line while the train is in gorund potential
(0 voltage) current starts flowing through his body,.
one more ex hav u ever seen a crow sittin on a single line
got eletricuted???? you could never see coz it is same
potential and there is no current flow through its body...
i hope u understand :)
