A particle of mass 0.5 kg is displaced from position \(\vec{r}_{1}\) (2, 3, 1) to \(\vec{r}_{2}\) (4, 3, 2) by applying a force of magnitude 30 N which is acting along \((\hat{i}+\hat{j}+\hat{k})\). The work done by the force is
- \(10 \sqrt{3} J\)
- \(30 \sqrt{3} J\)
- 30 J
- none of these
Answer
(B) 30 3 J
