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 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 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))

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 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 )

The force required to take away flat plate of radius 4cm from the surface of water is (surface tension os water =70"dyne"//cm)

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 = ----
