उत्तर
The pressure is given by P = h Xp Xg.
Where h is the height of the liquid column, p is the density of the liquid, g is the acceleration due to gravity.
Density of mercury is = 1.36 X104 kg/m3.
h = height of mercury column which is given = 75 cm = 0.75 m.
So pressure = 0.75 X 1.36 X104X9.8 = 9.996X104Nm-2.
