Question

In a hydraulic machine, a force of 4N is applied to the piston of the area 2p
of cross-section 10 square centimetre. The force applied on its piston of
the area of cross-section 100 square centimetre is
20 n
30 n
or 40 n
​

Answer 1

Answer:

$hii$

Explanation:

We know that, Pressure= Force/Area

⇒Pressure= 2/10 = 0.2 cm^-2

=0.2Ncm ^−2

Now, Pressure=0.2

Again, Force=Pressure×Area

Force=0.2×100=20N

Hence your answer is 20 N
