The correct option is B i.20 m,ii.0
Since the ball attains height of 10 m and comes back to the same position, we have the values for distance and displacement as
i. Distance is the total path length, so, it will be 10+10=20 m
and,
ii. as the ball returns to the same position, the initial and final positions are same, hence the displacement of the ball will be zero.
