A ring is cut from a platinum tube having 10 cm internal and 11 cm external diameter. It is supported horizontally from a pan of balance, so that it comes in contact with water in a glass vessel. What is the surface tension of water if an extra, 4.752gwt is required to pull it away from water ? `(g=10m//s^2)`

A

`7.2 xx 10^(-2) N//m`

B

`72 N//m`

C

`14.4xx 10^(-2)`

A ring is cut from a platinum tube of 8.5cm internal and 8.7cm external diameter. It is supported horizontally from a pan of a balance so that it comes in contact with the water in a glass vessel. The surface tension of water, if an extra 3.79g wt is required to pull it away from water, ( g= 980 cm//s^2 ) is found to be (71.77-x) dyne/cm, where x = ----

A ring is cut from a platinum tube of 8.5cm internal and 8.7cm external diameter. It is supported horizontally from a pan of a balance so that it comes in contact with the water in a glass vessel. If an extra 3.97g weight is required to pull it away from water, then surface tension of water is nearly (18.03) X dyne / cm. Find x (g=980cm/ s^2 )
