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 68)/10`

B

0 cm

C

`(76 xx 10)/68`

D

`(76 xx 10)/84`
