Question

The guage pressure exerted below a column
of water, open to the earth's atmosphere at
depth of 10 m is (density of water = 1000 kg/m®,
g= 10 m/s2 and 1 atm pressure = 105 Pa)
(1) 1 atm
(2) 2 atm
(3) 3 atm
(4) 4 atm​

Answer 1

Answer:

(1) 1 atm

Explanation:

atmoshpheric pressure need not be taken into account since it is at a depth below a surface hence

P = hdg (where h=height , d=density , g=acc due to gravity)

P = 10*1000*10

  = $10^{5}$

  = 1 atm
