If a capillary tube of radiusris immersed in a liquid, then the liquid rises to a heighth. The corresponding mass of liquid column ism. The mass of water that would rise in another capillary tube of twice the radius is

Options:

Answer:
A
Solution:

Force due to surface tension=2πrT

This force supports the weight

⇒2πrT=mg

⇒m∝r

As radiusrdoubles, weight supported will also doubles
