Q. In a certain situation, $\overrightarrow{\mathbf{F}}$ and $\overrightarrow{\mathbf{s}}$ are not equal to zero but the work done is zero. From this, we conclude that
A) $\overrightarrow{\mathbf{F}}$ and $\overrightarrow{\mathbf{s}}$ are in same direction
B) $\overrightarrow{\mathbf{F}}$ and $\overrightarrow{\mathbf{s}}$ are in opposite direction
C) $\overrightarrow{\mathbf{F}}$ and $\overrightarrow{\mathbf{s}}$ are at right angles
D) $\overrightarrow{\mathbf{F}} > \overrightarrow{\mathbf{s}}$
Explanation
The correct answer is Option C: $\overrightarrow{\mathbf{F}}$ and $\overrightarrow{\mathbf{s}}$ are at right angles.
