Question

When a capillary tube is immersed vertically in water the capillary rise is $3cm$. if the same capillary tube is inclined at angle of ${60}^o$ to the vertical, the length of the water column in the capillary tube above that of the outside level is

• A. $6cm$
  
• B. $1cm$
  
• C. $8cm$
  
• D. Zero
  

Answer 1

The correct option is A $6cm$

Vertical Capillary rise will be constant

$lcos{60}^0=h_1$

$l=2\times 3cm=6cm$
