A \( 10 \mathrm{~cm} \) long wire is placed horizontally on the surface of water and is gently pulled up with a force of \( 2 \times 10^{-2} \mathrm{~N} \). To keep the wire in equilibrium, the surface tension in \( \mathrm{Nm}^{-1} \) of water is
(a) \( 0.1 \)
(b) \( 0.2 \)
(c) \( 0.001 \)
(d) \( 0.002 \)
