A body is experiencing an atmospheric pressure of `1.01 xx 10^6 N//m^2` on the surface of a pound. The body will experience double of the previous pressure if it is brought to a depth of (given density of pound water `=1.03 xx 10^3 kg//m^2, g=10m//s^2)`

A

8 m

B

8.6 m

C

9.7 m

D

10.3 m

Text Solution

Verified by Experts

The correct Answer is:
C
Suppose, alr pressure on the surface=p and height = n
But pressure at h = air pressure + water pressure
`implies 2 p = p +hdg`
`p =hdg`
`1xx10^5 = h xx1.03 xx10^3 xx10`
`h =10^5 /(1.03 xx10^3xx10)=9.7m`
