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

Options

  1. A4 M
  2. B2 M
  3. CM 2
  4. DM

Correct answer

B. 2 M

Step-by-step solution

Mass of liquid rising in tube = ρ A h m = ρ π r 2 2 T cos ⁡ θ ρ g r m ∝ r Mass of liquid rise in tube will become 2 M
