A drop of water of volume \( V \) is pressed between the two glass placed so as to spread to an area \( A \). If \( T \) is the surface tension, the normal force required to separate the glass plates is
(1) \( \frac{T A^{2}}{V} \)
(2) \( \frac{2 T A^{2}}{V} \)
(3) \( \frac{4 T A^{2}}{V} \)
(4) \( \frac{T A^{2}}{2 V} \)
\( \mathrm{P} \)
