Question

Otto von Guericke, a German scientist of the 17th century, invented a pump to
extract air out of a vessel. With the help of this pump, he demonstrated
dramatically the force of the air pressure. He joined two hollow metallic
hemispheres of 51 cm diameter each and pumped air out of them. Then he
employed eight horses on each hemisphere to pull them apart (Fig. 11.20). So
great is the force of air pressure that the hemispheres could not be pulled apart.
