Question

6. What is the magnitude of a force which
produces a pressure of 7000 Pa while acting
on a surface of area of cross-section 0.25 m2?​

Answer 1

Answer:

pressure=force/area

Therefore area=force /pressure

area=300n/1500pa=1.5sq.m

Now 1m=100cm

Therefore 100x100/5=2000sq.cm

Answer 2

Answer:

The magnitude of Force is 1750 N.

Explanation:

According to question,

Pressure = 7000 Pa

Surface Area = 0.25 m^2

Magnitude of force = ?

now,

we know that, Pressure is force per unit area on a object.

i.e,

Pressure = Magnitude of Force / Surface Area

=> Magnitude of Force = Surface Area × Pressure

=> Magnitude of Force = 0.25 × 7000

= 1750 Newton.

hence, Magnitude of Force is 1750 N.
