A Satellite Revolves Round the Earth. Air Pressure Inside the Satellite is Maintained at 76 Cm of Mercury. What Will Be the Height of Mercury Column in a Barometer Tube - Physics


A satellite revolves round the earth. Air pressure inside the satellite is maintained at 76 cm of mercury. What will be the height of mercury column in a barometer tube 1 m long placed in the satellite?

Pressure at point A is 76 cm of mercury. Therefore, mercury will rise to full length of the tube, i.e., 1 m, to maintain equal pressure at points A and B. Inside the satellite, geffective = 0, so the pressure due to height of the mercury column will be zero.

  Is there an error in this question or solution?
