Q. Rubber suckers are usually used to hold objects with the help of suctions. Give reason?
Answer: When we press the sucker, most of the air between its cup and the surface escapes out. The sucker sticks to the surface because the pressure of atmosphere acts on it. If there is no air between the cup and the surface, than it would be impossible to pull the sucker off the surface.
