Answer:
1. When there is no force or no displacement.. or the direction of displacement is perpendicular to the direction of force then the work done is zero.
2. When the displacement is zero OR
when the force acts at right angles to the
direction of the displacement then
the work done is zero.

ANSWER
Two conditions when the work done is zero are:
(i) When there is no displacement (S=0) and,
(ii) When the displacement is nonual to the direction of the force (θ=90^o).
