The work done by a force

\mathbf{F}

during a displacement

\mathbf{r}

is given by

\mathbf{F}\cdot\mathbf{r}

. Suppose a force of

12\,\text{N}

acts vertically upward on a particle, and the particle is displaced

2.0\,\text{m}

vertically downward. Find the work done by the force during this displacement.
