11. A drop of some liquid of volume \(0.04 cm ^3\) is placed on the surface of a glass slide. Then another glass slide is placed on it in such a way that the liquid forms a thin layer of area \(20 cm ^2\) between the surfaces of the two slides. To separate the slides, a force of \(16 \times 10^5\) dyne has to be applied normal to the surfaces. The surface tension of the liquid is (in dyne- \(cm ^{-1}\) )  📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
