Determine the surface tension forces in case a ring of radius 10cm is placed on a water surface(surface tension of water = 7×10−2N/m;π=227)
Raghu had to make a cylindrical aluminium tube. What is the area of the aluminium sheet required to make the tube if the length of the tube is 1 m and base radius is 3.5 cm? [Take π=227]
Determine the surface tension forces in case an annular disc of radii r1 and r2 is placed on the water surface (surface tension of water T = 7×10−2N/m;π=227)
