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
Correct Answer: Option D
Explanation
pressure at H = 40m ; pressure at G, p1 = 20m
(frac{p_1}{p_1}) = (frac{40}{20})
= 2
