The neck and bottom of a bottle have diameters 2cm and 8cm respectively. The bottle is completely filled with kerosine. If the cork in the neck is preseed with a force of 10N , what force is exerted on the bottom of the bottle ​

Answer» RADIUS of the cork at the NECK is 1cm.Area of the cork,Ac=π×21 2So, pressure applied through the cork,Pc=π×121.2kgf.cm−2Same pressure is applied on the bottom of the bottle as PER PASCAL's law.Radius of the bottom of bottle is 5cm.Area of the bottom,Ab=π×25 2So, force applied at the bottom =Pc× Ab=π×121.2×π×5 21.2×25=30kgf
