A long capillary tube of mass `pi` gm, radisu `2mm` and negligible thickness, is partially immersed in a liquid of surface tension `0.1(N)/(m)`. Take angle of contact zero and neglect buoyant force of liquid. The force required to hold the tube vertically, will be `(g=10(m)/(s^2)`)
A. `10.4pimN`
B. `10.8pimN`
C. `0.8pimN`
D. `4.8pimN`
