Two drops of the same radius are falling through air
P with a steady velocity of \( 5 \mathrm{~cm} / \mathrm{s} \). If the two drops

W coalesce. the terminal velocity would be
(1) \( 10 \mathrm{~cm} / \mathrm{s} \)
(2) \( 2.5 \mathrm{~cm} / \mathrm{s} \)
(3) \( 5(4)^{1 / 3} \mathrm{~cm} / \mathrm{s} \)
(4) \( 5(3)^{1 / 3} \mathrm{~cm} / \mathrm{s} \)
