Can a rubber sucker be stuck on a rough surface?

Open in App

Solution

The sucker sticks to the surface because the pressure of atmosphere acts on it. Incase of rough surface all the air between the cup and the surface does not escape and exerts pressure on the inner walls of the cup, hence it does not stick to the surface
