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

Text Solution

AI Generated Solution

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 ...
