Question:medium

If $\overline{a}$ is constant vector then $\nabla \times (\overline{a} \times \overline{r}) = _?$

Show Hint

For constant $\overline{a}$, the curl of $(\overline{a} \times \overline{r})$ is always $2\overline{a}$.
  • $\overline{a}$
  • $2\overline{a}$
  • $3\overline{a}$
  • $\overline{0}$
