361145 Two identical soap bubbles are combined isothermally to form a big bubble of radius \(R\). If \(V\) and \(S\) are changes in volume and area and \(P_{o}\) is atmospheric pressure then the correct relation is

1 \(3 P_{o} V+4 T S=0\)
2 \(P_{o} V+T S=0\)
3 \(P_{o} V+4 T S=0\)
4 \(4 P_{o} V+3 T S=0\)

361146 A long capillary tube of radius \(0.2\;mm\) is placed vertically inside a beaker of water of surface tension \(0.07\;N{\rm{/}}m.\) Water due to zero angle of contact rises upto height of \(7.05\;cm\) in tube. Now if tube is pushed into water so that only \(5\;cm\) of its length is above the surface, find new angle of contact in degrees between water and glass surface. (Take \(\sqrt{2}=1.41\) )
