Homework Statement
On Earth a certain apparatus can safely dive to a depth of 275m in a freshwater lake. This limitation is due to the external gauge pressure on the apparatus. If this device were to be used in a lake on Mars, where the acceleration due to gravity is 3.70m/s^2 but the denisty of water is essentially the same as on earth, the greatest depth to which it could safely dive is closest to
1930m
728m
169m
448m
104m
Homework Equations
p=p0+dgh
The Attempt at a Solution
I calculated the pressure of the Earth dive to be 1.04*10^5pa using p=1.013*10^5+9.81*1*275. I know the g value for Mars will be different and I think the atmospheric pressure on Mars is different but is there a way to calculate the atm pressure of mars? Or am I to solve the problem without using either atmospheric pressures?
