Question

A capillary tube when immersed vertically in a liquid records a rise of 8 cm. If the tube is immersed inclined 60° with the vertical, then length of liquid column along the tube will be ____________.

Options

• `2 sqrt3  "cm"`

• 16 m

• `2/sqrt3  "cm"`

• 12 cm

Answer 1

A capillary tube when immersed vertically in a liquid records a rise of 8 cm. If the tube is immersed inclined 60° with the vertical, then length of liquid column along the tube will be 16 m.

Explanation:

`l = "h"/("sin"(90 - theta))`

`= "h"/("sin"  30°) = 8/(1//2)`

` = 16  "cm"`
