Answer 2

$\sf\huge\bold{Answer:}$

Given :

Force applied(F) = 100N

Area(A) = 200cm²

To find :

Pressure acting in the given area

Solution :

$\fbox{Formula used}$

$\sf\red{ :⟶pressure(p) = \frac{force(F)}{area(A)} }$

Force applied(F) = 100N

Area(A) = 200cm²

Area into m²

1cm=0.01m

1cm²=0.0001m²

200cm²=200×0.0001m² = 0.02m²

$\sf{ :⟶pressure(p) = \frac{100N}{0.02m²} }$

$\sf{ :⟶pressure(p) = \frac{100N×100}{2m²} }$

$\sf{ :⟶pressure(p) = }$$\displaystyle{\sf { \cancel{ \frac{100}{2} }}}$$\sf{×100N/m²}$

$\sf{ :⟶pressure(p) = 100×50N/m² or Pa }$

$\sf{ :⟶pressure(p) = 5000N/m² or Pa }$

$\sf{ :⟶pressure(p) = 5×10³N/m² or Pa }$

$\fbox{10³Pa(pascal) = 1kPa (kilopascal)}$

$\sf{ :⟶pressure(p) = 5kPa }$

$\sf\huge\purple{ pressure(p) = 5kPa }$
