Solution :-
Case I
In this case, the direction of force functioning on the block is perpendicular to the displacement. Therefore, work done by force on the block are going to be zero.
Case II
In this case, the direction of force functioning on the block is within the direction of displacement. Therefore, work done by force on the block are going to be positive.
Case III
In this case, the direction of force on the block is contrary to the direction of displacement. Therefore, work done by force on the block are going to be negative.
