Question

calculate the force which is applied to an area of 25cm square to produce a pressure of 20 pascal

Answer 1

$\huge{\mathcal{\green{Answer}}}$

$pressure = \frac{force}{area} \\ .................. \\ 20pascal = \frac{force}{25cm {}^{2} } \\ 25 \times 20 = force$

$\huge{\mathcal{\blue{force=500n}}}$

Answer 2

We know presure is equal to force upon area.

Pa=force/area

20=force/25 cm

20*25=force

500=force

Therefore, force is 500 Newton.
