A capillary tube of radius R is immersed in water and water rises in it to a height H . Mass of water in the capillary tube is . M If the radius of the tube is doubled, mass of water that will rise in the capillary tube will now beCorrectIncorrect
If the surface of a liquid is plane, then the angle of contact of the liquid with the walls of container isCorrectIncorrect
A capillary tube when immersed vertically in a liquid records a rise of 3 cm. if the tube is immersed in the liquid at an angle of 60° with the vertical, then length of the liquid column along the tube will beCorrectIncorrect
A capillary tube of radius r can support a liquid of weight 6.28 × 10–4 N. if the surface tension of the liquid is 5 × 10–2 N/m. the radius of capillary must beCorrectIncorrect
Water rises in a capillary tube to a certain height such that the upward force due to surface tension is balanced by 75 × 10–4 N, forces due to the weight of the liquid. If the surface tension of water is
6 × 10–2 N/m, the inner-circumference of the capillary must beCorrectIncorrect
Amount of energy required to blow a bubble of radius 5 cm, is (Surface tension of soap is 30 × 10–2 N/m)CorrectIncorrect
5 g of water rises in the bore of capillary tube when it is dipped in water. If the radius of bore capillary tube is doubled, the mass of water that rises in the capillary tube above the outside water level isCorrectIncorrect
Work done in blowing a liquid drop to radius R is W1 and that to radius 3R is W2. the ratio of work done isCorrectIncorrect
A square frame of side l is dipped in a liquid soap when it is taken out of the liquid, a film is formed on it. If surface tension is T then force acting on it isCorrectIncorrect
Two capillary tubes of the same material but of different radii are dipped in a liquid. The heights to which the liquid rises in the two tubes are 2.2 cm and 6.6 cm. the ratio of radii of the tubes will beCorrectIncorrect
