Suppose the glass of the previous problem is covered by a jar and air

1.	Suppose the glass of the previous problem is covered by a jar and air inside the jar is completely pumped out a. What will be the answer to the problem? b.Show that the answers do not change if a glass of different shape is used provided the height, the bottom area and the volume are unchanged.
Answer» SOLUTION :If the glass WIL be covered by a jar and the air is pumped out the atmospheric pressure had no effect so a. FORCE exerted on the bottom `=(hrho_ug)xxA` `=(20xx10^-2xx10^-3xx10)20xx10^-4` =4N` b. `mg=hxxrho_wxxgxAxxF_s` `rarr F_s=5-4=1N` `c. If glasses of differet shapes used have the same volume height and area no CHANGE in ANSWER will occur.
