A small but heavy block of mass \( 10 \mathrm{~kg} \) is attached to a wire \( 0.3 \mathrm{~m} \) long. Its breaking stress is \( 4.8 \times 10^{7} \mathrm{~N} / \mathrm{m}^{2} \). The area of the cross section of the wire is \( 10^{-6} \mathrm{~m}^{2} \). The maximum angular velocity with which the block can be rotated in the horizontal circle is
(1) \( 4 \mathrm{rad} / \mathrm{s} \)
(2) \( 8 \mathrm{rad} / \mathrm{s} \)
(3) \( 10 \mathrm{rad} / \mathrm{s} \)
(4) \( 32 \mathrm{rad} / \mathrm{s} \)
