361315 What is the radius of the biggest aluminium coin of thickness, \(t\) and density \(\rho\), which will still be able to float on the water surface of surface tension \(S\) ?

361316 A ring is cut from a platinum tube of \(8.5\;\,cm\) internal and \(8.7\;cm\) external diameter. It is supported horizontally from a balance so that it comes in contact with the water in a glass vessel. What is the surface tension of water if an extra \(3.97\;\,g\) weight is required to pull it away from water ? \(\left( {g = 980\;cm/{s^2}} \right)\)

361317 A \(10\;cm\) long wire is placed horizontally on the surface of water and is gently pulled up with a factor of \(2 \times {10^2}\;N\) to know the wire in equilibrium. The surface tension, in \(N{m^{ - 1}}\) of water is

361318 A metal wire of density \(\rho\) floats on water surface horizontally. For it not to sink in water maximum possible radius of wire should be \(\frac{{{T^n}}}{{\sqrt {\pi \rho g} }}\) where, \(T\) is surface tension of water. Find \(n\).
