Calculate the work done if a particle displaces through `(3hati-hatj+6hatk)` meter under a force `(hati+hatj-hatk)` newton. (work`=vecF.vecs`)

Explanation

To calculate the work done by a force when a particle displaces, we use the formula:

\[ W = \vec{F} \cdot \vec{s} \]

where \( W \) is the work done, \( \vec{F} \) is the force vector, and \( \vec{s} \) is the displacement vector.
