One metre long tube, closed at both ends, is lying horizontally. A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg)

View answer and explanation

Correct option: C

0.029 m

Option C (0.029 m) is correct because it is calculated by applying Boyle's law to the air columns and considering the pressure difference due to the mercury column.
