Answer:
It less than doubles.
Explanation:
It is given that,
You are originally 1.0 m beneath the surface of a pool, h = 1 m
If you dive to 2.0 m beneath the surface, h' = 2 m
The absolute pressure acting on the person is given by :
[tex]P=P_a+\rho gh[/tex]
[tex]P_a[/tex] is the atmospheric pressure
If h = 1
[tex]P_1=P_a+\rho g[/tex]
[tex]P_1=1.013\times 10^5+1000\times 9.8[/tex]
[tex]P_1=111100\ Pa[/tex]
If h = 2
[tex]P_2=P_a+2\rho g[/tex]
[tex]P_2=1.013\times 10^5+1000\times 9.8\times 2[/tex]
[tex]P_2=120900\ Pa[/tex]
When the height becomes doubles, the absolute pressure on you becomes less than doubles. Hence, the correct option is (B).
