Question

*They're all copying and pasting, why is the answer Assuming an average weight of 80 kg/person, it would take the weight of 100 people to separate spheres

about this In 1656, Otto von Guericke of Magdeburg presented his invention, a vacuum pump, through a demonstration that became a popular sensation. A metal sphere made of two hemispheres (now known as the Magdeburg hemispheres) was evacuated, so that a vacuum would hold the two pieces together. Von Guericke would then have several horses (by one account, 30 of them, in two teams of 15) pulling, unsuccessfully, to separate the hemispheres. The demonstration would end with the opening of a valve that removed the vacuum and allowed the hemispheres to separate. Suppose that the diameter of the sphere is 1 m and the sphere is completely evacuated. The sphere is hung from the ceiling and you pull the other half with the force of your body weight. Will the hemispheres come apart? Support your answer with calculations.

!!Again, please do not copy and paste. The answer was different l'd like you to write a little better!!

Answer 1

using condition at vaccum and balancing force due to atmosphere and weight we can state whether spheres will be puleld apart or not.

for any discussion on solution please write in comments as i have approached it logically no plagirism.
