Question:medium

If \( M \) is the mass of water that rises in a capillary tube of radius \( r \), then the mass of water which will rise in a capillary tube of radius \( 2r \) is:

Show Hint

The mass of water in a capillary tube depends linearly on the radius of the tube. Doubling the radius of the capillary will double the mass of the water it holds.
