#### Explanation:

The pressure exerted by a static fluid depends only upon height

The pressure in a static fluid is given by the expression

- At the surface the pressure is due to atmosphere.
- At depth
#h# pressure is sum of pressure due to air and pressure due to water column of depth#h#

#P_h=Air+"pressure due to water of depth "h#

Inserting given values we obtain

#3Atm=1Atm+"pressure due to water of depth "h#

#=>"pressure due to water of depth "h=3-1=2Atm# #:."pressure due to water of depth "2h=2xx2=4Atm#

Now#P_(2h)=Air+"pressure due to water of depth "2h#

Inserting calculated value we obtain

#P_(2h)=1+4=5Atm#
