Your fingers hold water in a straw. You insert a straw of length L into a a tall glass of your favorite beverage. You place your finger over the top of the straw so that no air can get in or out., and then lift the straw from the liquid. You find that the straw retains the liquid such that the distance from the bottom of your finger to the top of the liquid is h. Does the air in the space between your finger and the top of the liquid have a pressure P that is (a) greater than, (b) equal to, or (c) less than, the atmospheric pressure P A outside the straw?
