Question

If the length of a tube is less and cannot accommodate the maximum rise of liquid, then

• A. Liquid will form a fountain
• B. Liquid will not rise
• C. The meniscus will adjust itself so that the water does not spill
• D. None of the above

Answer 1

The correct option is C The meniscus will adjust itself so that the water does not spill

We know for capillary tube of insufficient length,
$hR=h^{\prime }{R}^{\prime }$
$\therefore$ If the height of tube is insufficient, the radius of meniscus changes to ensure that no spilling occurs.
