Answer» The total pressure on the swimmer would be the sum of the atmospheric pressure and the pressure due to 10m colum of water so, P = Patm+ ρgh here Patm= 10^5N/m^2 ρ (of water) = 1000 kg/m^3 g = 9.81 m/s^2 h = 10m thus, we have P = 10^5+(1000x9.81x10) so, total pressure P = 1.981 x 10^5N/m^2 |
