Question

A capillary tube when immersed vertically in a liquid records a rise of $3cm$. if the tube is immersed in the liquid at an angle of ${60}^o$ with the vertical, then length of the liquid column along the tube will be:

• A. $2cm$
  
• B. $3cm$
  
• C. $6cm$
  
• D. $9cm$
  

Answer 1

The correct option is C $6cm$

So $lcos{60}^0=3cm$

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