THERE IS NO FRICTION BETWEEN THE MANS FOOT AND PLANK.
WHEN MAN WILL PULL THE BOX THEN ACTION-REACTION LAW CAN BE APPLIED.
NOW THERE IS NO FRICTION B/W MAN AND BLOCK WHILE BLOCK &GROUND EXERT FRICTION. THEN FORCE OF STRING WILL BE EFFECTIVE AND IT WILL PULL THE MAN TOWARDS IT SELF.
HENCE MAN WILL SLIDE AND SO HE CAN'T PULL THE BLOCK.
