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))`

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 circle ring of radius 7cm is supported horizontally from the pan of a balance,so that it comes in contact with water in a glass vessel.The force required to detach it from the surface of water will be (surface tension of water will be 0.072N/m )

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)
