Here, we will solve a Numerical problem based on Capillary Rise & Capillarity.

Numerical assignment (on Capillary Rise & Capillarity) solved

1)
A glass tube of radius 0.4 mm is dipped vertically in the water.

Find up to what height, the water will rise in the capillary.

If the tube is inclined at an angle of 60° with the vertical, how much length of the capillary is occupied by water?
(Take, the surface tension of water = 7.0 × 10⁻² Nm⁻¹ and density of water = 10³ kg m ⁻³ )

Solution:
