Question

A capillary tube when immersed vertically in a liquid records a rise of 6 cm. If the tube is immersed in the liquid at an angle of 60° with the vertical, then length of the liquid column along the tube will be ______.

Options

• 12 cm

• 3 cm

• 6 cm

• 9 cm

Answer 1

A capillary tube when immersed vertically in a liquid records a rise of 6 cm. If the tube is immersed in the liquid at an angle of 60° with the vertical, then length of the liquid column along the tube will be 12 cm.

Explanation:

`l = "h"/ ("sin"  theta) = 6/("sin"  30^circ) = 6/((1/2))`

= 12 cm
