A ring is cut from a platinum tube `8.5 cm` internal and `8.7 cm` external diameter. It is supported horizontally from the pan of a balance, so that it comes in contact with the water in a glass vessel. If an extra `3.103 gf` is required to pull it away from water, the surface tension of water is

A ring is cut from a platinum tube 8.5 cm internal and 8.7 cm 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 3.97 gm-wt. is required to pull it away from water, the surface tension of water is

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 )

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 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 thin metal ring of internal radius 8 cm and external radius 9 cm is supported horizontally from the pan of a balance so that it comes in contact with water in a glass vessel. If is found that an extrea weight of 7.48g is required to pull the ring out of water. The surface tension of water is (g=10m//s^(2))
