Neglecting the density of air, the terminal velocity obtained by a raindrop of radius \( 0.3 \mathrm{~mm} \) falling through the air of viscosity \( 1.8 \times 10^{-5} \mathrm{~N} / \mathrm{m}^{2} \) will be
(1) \( 10.9 \mathrm{~m} / \mathrm{s} \)
(2) \( 8.3 \mathrm{~m} / \mathrm{s} \)
(3) \( 9.2 \mathrm{~m} / \mathrm{s} \)
(4) \( 7.6 \mathrm{~m} / \mathrm{s} \)
