A point charge \( q_{1} \) is placed inside cavity 1 and another point charge \( q_{2} \) is inside cavity 2 . A point charge \( q \) is placed outside the conductor. For the situation described above, answer the following questions.
\( \vec{E} \) inside the conductor at point \( S \) distant \( r \) from point charge \( q \), due to charge on outer surface of the conductor, would be
(1) \( \left(Q+q_{1}+q_{2}\right) / 4 \pi \varepsilon_{0} r^{2} \) away from charge \( q \)
(2) \( q / 4 \pi \varepsilon_{0} r^{2} \) toward charge \( q \)
(3) zero
(4) cannot be determined
