Given
weight of chair with person on it =2118 N
Barber applies a force of 63 N
Using pascal's law
we know pressure around both sides is equal
i.e. 
pressure=
=
=
substituting values
![\left [\frac{r_{plunger}^2}{r_{piston}^2}\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7Br_%7Bplunger%7D%5E2%7D%7Br_%7Bpiston%7D%5E2%7D%5Cright%20%5D)
=
