Question

The diameter of neck and bottom of a bottle are 2 cm and 10 cm respectively. The bottle is completely filled with oil. if the cork in the neck is pressed in with a force of 1.2 kgf , What force is exerted on the bottom of the bottle ?

Answer 1

Answer:

1 kgf=10N

1.2kgf=120N

2cm=2/100m

10cm=1/10m

according to pascal law p1=p2

f/a=f2/a2

120*100/2=f2*10/1

6000/10=f2

f2=600N

pressure 2=600*10/100

p2=60 pascal

p1=120/2

p1=60pascal
