If \( \vec{a} \) and \( \vec{b} \) are perpendicular, then
\( \mathrm{P} \) \( \vec{a} \times(\vec{a} \times(\vec{a} \times(\vec{a} \times \vec{b}))) \) is equal to:

W.
(1) \( \frac{1}{2}|\vec{a}|^{4} \vec{b} \)
(2) \( \overrightarrow{0} \)
(3) \( \vec{a} \times \vec{b} \)
(4) \( |\vec{a}|^{4} \vec{b} \)
