A 10 cm column of air is trapped by a column of mercury, 8 cm long, in a capillary tube horizantally fixed as shown below, at 1 atm pressure. When the tube is held at certain angle `theta^(@)` , with open end up, the weight of Hg is borne partially by the gas. Vertical Height of Hg is a measure of additional pressure on gas:

The length of air coloumn.when the tube is fixed vertically at the same temperature wth open end up is

A

`(76 xx 84)/10 cm`

B

`(76 xx 10)/84` cm

C

A 10 cm column of air is trapped by a column of mercury, 8 cm long, in a capillary tube horizontally fixed as shown below, at 1 atm pressure. When the tube is held at certain angle theta^@ with open end up, the weight of Hg is borne partially by the gas. Vertical Height of Hg is a measure of additional pressure on gas. When the tube's held at 45^@ with the horizontal with open end up the length of air column is

Why is the height of mercury column nearly 76 cm in the tube ?

When a capillary tube is dipped in water vertically, water rises to a hcight of 10 mm. The tube is now titled and makes an angle 60^(@)C with vertical. Now length of water column in tube is,
