Question

A pressure of 10 kPa acts on an area of 300 cm² the force acting on the area will be :​

Answer 1

Answer:

300 N is the Force acting on the area.

Explanation:

Given:

Pressure = 10 kPa

Let us convert it to Pa from kPa

kPa means Kilo Pascals.

1 kPa = 1000 Pa

So, the given value of Pressure , P = 10000 Pa

Area = 300 $cm^2$

Let us convert it to $m^{2}$.

10000 $cm^2$  = 1 $m^{2}$

So, Given Area, A = 0.03 $m^{2}$

To find:

The force acting on the area = ?

Solution:

Formula for Pressure is given as:

$P = \dfrac{F}{A}$

Where F is the Force and

A is the Area.

$\Rightarrow 10000 = \dfrac{F}{0.03}\\\Rightarrow F = 10000 \times 0.03\\\Rightarrow F = 300\ N$

$\therefore$ Force acting on the area = 300 N.
