Answer ⇒ Height will be 1 m.
Explanation ⇒ In the satellite, the value of g is zero, this means there will be the weightlessness.
Thus, the weight of the mercury column will automatically be zero.
This also means the column has no pressure at the level of the reservoir to balance the outer pressure of 76 cm of mercury or or 1 atmosphere pressure.
Therefore the level of the mercury in the barometer tube will not fall and it will remain 1 m.
Hence, the level of the Mercury is 1 m.
Hope it helps.
