The gravitational force exerted by an object is given by F= mg where F is the force in newtons, m is the mass in kilograms, and gg is the acceleration due to gravity, 9.81m/s^2 .Calculate the force exerted per unit of area by a column of mercury (density = 13.59g/cm^3) that is 76.0cm high. How high would a column of water (density =1.00g/cm^3) have to be to exert the same force?
