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 be

Options

A. M
B. 2M
C. M/2
D. 4 M

Answer

B

Explanation

Mass of liquid in capillary tube
`M=piR^(2)Hxxrho`
`thereforeMpropR^(2)xx((1)/(R))" "(AsH prop 1//R)`
`thereforeMpropR.` If radius becomes double, then mass will becomes twice.
