Question

The rise of liquid in a sufficiently long capillary tube depends upon

• A. the outer of the tube
• B. the inner radius of the tube
• C. the nature of material of the tube
• D. the length of the tube

Answer 1

Answer: (B), (C)

The correct options are
B the inner radius of the tube
C the nature of material of the tube

Rise of liquid in capillary tube $h=\frac{2T}{PgR}$

Where

$T-$ Surface tension

$P-$ Density of material

$R-$ Radius (inner) of the tube.
