Answer 1

Answer:

The required force will be of 20 N

Explanation:

In a simple way,

force req. for 10cm²=2N

-------------------1cm²=2/10

=0.2N

so, for 100N

=100×0.2

we get,

20N --ans.

hope u get it.

Answer 2

Answer:

Question :

In a hydraulic pressure machine, a force of 2 N is applied on the piston of area of cross section 10cm². What force is obtained on its piston of area of cross section 100cm²?

Answer :

$Force \: needed \: for \: 10 {cm}^{2} \: = \: 2N \\ \\ Force \: needed \: for \: 1 {cm}^{2} \: = \: \frac{2}{10} = 0.2 N\\ \\ Force \: needed \: for \: 100 {cm}^{2} = 100 \times 0.2 \\ \\ = 20N \\ \\ \\ Therefore \: the \: answer \: is \: 20N.$
