Question

The area of cross section of the end A of a U tube is 0.01 m square. The area of cross section at the end B is 0.1 m square. If 100 N is applied on the piston,

A . Find out the force acting on the piston at the end B.
​

Answer 1

• Area=0.1m^2(B),0.01m^2(A)
• Force=100N,F1

`\\ \rm\longmapsto Pressure=(Force)/(Area)`

`\\ \rm\longmapsto(F_1)/(F_2)=(A_1)/(A_2)`

`\\ \rm\longmapsto F_1=A_1F_2/A_2`

`\\ \rm\longmapsto F_1=(0.1(100))/(0.01)`

`\\ \rm\longmapsto F_1=(10)/(0.01)`

`\\ \rm\longmapsto F_1=1000N`
