two divers G and H are at depths of 20 and 40 relatively below the water in a lake
that is to say that
G=20 and H=40
if the pressure G = p1 and H = p2 the value of p2/p1 is ?
note that they gave us an atmospheric pressure equivalent to 10m of water
that is to say
p2+10/ p1+10
which is 40+10/ 20+10 = 50/30
which is = 1.67
