A capillary tube of radius r is immersed in water and water rises in ...
Explanation:
Capillary rise in a tube:
- The capillary rise in a tube is given by the formula: h = (2Tcosθ)/(ρgr)
- Where h is the height of the liquid rise, T is the surface tension of the liquid, θ is the contact angle, ρ is the density of the liquid, g is the acceleration due to gravity, and r is the radius of the tube.
Given data:
- For the first capillary tube, radius = r, mass of water = 5g
- For the second capillary tube, radius = 2r
Calculating the mass of water in the second tube:
- Since the radius of the second tube is 2r, the height of water rise will be h' = (2Tcosθ)/(ρg(2r))
- Mass of water in the second tube can be calculated using the formula: m' = π(2r)^2 * h' * ρ
- Substituting the value of h' in the above equation and simplifying, we get: m' = 4 * π * h * ρ = 4 * 5g = 20g
Therefore, the mass of water that will rise in the second capillary tube with a radius of 2r is 20.0g, which corresponds to option (B).

A capillary tube of radius r is immersed in water and water rises in ...
Force of surface tension balances the weight of water in capillary tube.
FS = 2πrT cosθ = mg
Here, T and θ are constant.
So, m ∝ r
Let m1 and m2 be the mass of water in two capillary tube.
