Question

A force of 150 N is applied on an object of area 0.001 m². How much pressure will it exert?

Answer 1

Answer:

Force applied on the object= 150N

area of contact= 0.001m^2

pressure = force/area

(150/0.001)Nm^-2

150,000Nm^-2. (as the force is applied on a very small area.)

Answer 2

▪︎ Given:-

• Force = 150 N.

• Area = 0.001 m².

▪︎ Formula Used:-

$\sf \mapsto \: pressure = \frac{force}{area}$

▪︎ Now,

• The required pressure,

$\sf = \frac{150}{0.001} \: pascal \\ \\ \: \sf = \frac{150}{1 \times 10 {}^{ - 3} } \: pascal \\ \\ =\sf \frac{150 \times 1000}{1} \: pascal \\ \\\sf \large \fbox\red{ = 150000 \: pascal}$

☆ Therefore the pressure is 150000 pascals.
