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 P2/P1 is?
0.50
0.60
1.67
2.00
Correct answer is C
Atmospheric pressure equivalence of 10m of water
: p2+10p1+10
= \frac{40+10}{20+10
= 5030 = 1.67
