work done when a force $\overrightarrow{\mathrm{F}}=(\hat{\mathrm{i}}+2\hat{\mathrm{j}}+3\hat{\mathrm{k}})\mathrm{N}$ acting on a particle takes it from the point $\overrightarrow{{\mathrm{r}}_1}=(\hat{\mathrm{i}}+\hat{\mathrm{j}}+\hat{\mathrm{k}})$ to the point $\overrightarrow{{\mathrm{r}}_2}=(\hat{\mathrm{i}}-\hat{\mathrm{j}}+2\hat{\mathrm{k}})$ is:

• A

  -3 J

• B

  - 1 J

• C

  zero

• D

  2 J
