Two drivers G and H are at depths 20m and 40m, respectively below the water surface in a lake. The pressure on G is O\(_1\) while the pressure on H is P\(_2\), If the atmospheric pressure is equivalent to 10m\(^2\) of water, then the value of P\(_2\)/P\(_1\) is
A
0.50
B
0.60
C
1.67
D
2.00
correct option: d
Pressure at H = 40m
Pressure at G, P\(_1\) = 20m
\(\frac{P_2}{P_1} = \frac{40}{20}\)
= 2
