Two divers G and H are at depths 20m and 40m respectively below the water surface in a lake. The pressure on G is P1 while the pressure on H is P2. If the atmospheric pressure is equivalent to 10m of water, then the value of \( \frac{p_2}{p_1} \) is?
A
0.50
B
0.60
C
1.67
D
2.00
E
3.0
Verified Correct Answer: C.
Physical Principles & Numerical Solution
pressure at H = 40m ; pressure at G, p1 = 20m
\(\frac{p_1}{p_1}\) = \(\frac{40 + 10}{20 + 10}\)
= \(\frac{50}{30}\)
≈ 1.67
