Problem

A laboratory vacuum chamber door must seal against an internal absolute pressure of

5.6\times10^{4}\,\text{Pa}

while the external atmospheric pressure is

1.01\times10^{5}\,\text{Pa}

. If the door is a rectangle measuring

0.40\,\text{m}

0.60\,\text{m}

, determine the net force exerted on the door by the air pressure difference.
