Question

a
In a hydraulic brake, a force of 500 N is
applied to a piston of area 5 cm?.
a) What is the pressure transmitted through out the liquid?
b) If the other piston has an area of 20 cm?,
What is the force exerted on it?

Answer 1

Answer:

We know that, Pressure=

Area

Force

⇒Pressure=

10

2

=0.2Ncm

−2

Now, Pressure=0.2

Again, Force=Pressure×Area

Force=0.2×100=20N
