A glass capillary of radius 0.35 mm is inclined at 60^ with the vertical in water. The height of the water column in the capillary is (surface tension of water =7 10⁻² ~N / m , acceleration due to gravity, g =10 ~m / s ^2, 0^ =1, 60^ =0.5 )
Options
- A6 cm
- B8 cm
- C10 cm
- D12 cm
Correct answer
B. 8 cm
Step-by-step solution
aligned & array l h = 2 ~T rgg = 2 (7 10⁻² ) 0^ (0.35 10⁻³ ) 10^3 10 ( =0^ , for glass-water ) h =0.04 ~m l= h array aligned where is angle of capillary with vertical as shown in figure. l= 0.04 (60) =0.08 ~m =8 ~cm
