An old story tells of a Dutch boy who used his fist to plug a 2.0-cm-diameter hole in a dike that was3.0 m below sea level, thus preventing the flooding of part of Holland. The atmospheric pressure is 1.0x105N/m2.
Part A. Determine the pressure in the water at the location of the hole. Express your answer to two significant figures and include the appropriate units.
Part B. Determine the force exerted on the boy's fist by the water. Express your answer to two significant figures and include the appropriate units.
