Work done by a force is zero when a body gets displaced along a direction `………..` to the direction of applied force .

Explanation

To solve the question, we need to determine the direction in which the work done by a force is zero when a body is displaced.

### Step-by-Step Solution:

1. **Understanding Work Done**:
The work done (W) by a force (F) on an object when it is displaced (S) is given by the formula:
\[
W = F \cdot S = F S \cos \theta
