At a depth of 500m in an ocean (a) what is the absolute pressure? (b) What is the gauge pressure? Density of sea water is `1.03 xx 10^(3) kg//m^(3), g=10ms^(-2)`. Atmospheric pressure = ` 1.01 xx 10^(5)Pa`.

A

40 atm

B

52 atm

C

32 atm

D

62 atm

Text Solution

Verified by Experts

The correct Answer is:
B

Absolute pressure `p=p_(a)+ rho gh`
here `p_(a)=1.01xx10^(5) Pa`
`rho=1.03xx10^(3) kgm^(-3)`
`therefore " " p=1.01xx10^(5) Pa+ 51.5xx10^(5) Pa`
`=1.01xx10^(5) Pa + 51.5xx10^(5) Pa`
`=52.5xx10^(5) Pa=52 atm`
