Consider a small surface area of 1mm2at the top of a mercury drop of radius 4mm. find the force exerted by the mercury below it. 2] The lower end of a capillary tube of radius 1mm is dipped vertically into mercury. find the depression of mercury column in the capillary 3] A wire forming a loop is dipped into soap solution and taken out so that a film of soap solution is formed. A loop of 6.28 cm long thread is gently put on the film and the film is pricked with a needle inside the loop. The thread loop takes the form of a circle. Find the tension in the thread. Surface tension of soap solution=0.030 N/m Please give a detailed solution Thank you.
