Question 18. Water rises up to a height h, in a capillary tube of radius r. the mass of the water lifted in the capillary tube is M. if the radius of the capillary tube is doubled, the mass of water that will rise in the capillary tube will be (a) M (b) 2M (c) M/2 (d) 4M
Where h is the height to which the water rises in the tube and 'r' is its radius. So, if the radius of the tube is doubled, mass of the water will become 2M, which will rise in the capillary tube.
