... a) The force on the plug from the water inherently includes the atmosphere above it, so we use the absolute pressure. Pabs = Po + ρgh = 1.01x105 + (1025)(9.8)(20m) = 3x105 Pa The force is then found with P = F/A 3x105 = F / (4x10-5) F = 12 N Note: This calculation of pressure (ρgh) only works sinc ...
