Question

if a force of 100 dyne is applied over an area of 2 cm2.Calculate the pressure produced in pascal

Answer 1

Answer:  

          0.50 Pascals

Explanation:

         Force = 100 dyne

          Area  = $2cm^2$

           1 cm  = 1/100cm

            $1 cm^2$  = 1/100x100 = 1/10000$cm^2$

            $2cm^2$  = 2/10000 $cm^2$    

    Pressure  = Area/Pressure

            P       = 100/2/10000

P x 10000    = 100/2

           P        = 50/10000

           P        =  0.0050

           P        =  0.50  

       

           

Answer 2

The pressure produced in Pascal is 5 Pascal.

Given:

A force of 100 dynes is applied over an area of 2 cm2.

To Find:

The pressure produced in Pascal.

Solution:

To find the pressure produced in pascal we will follow the following steps:

As we know,

Pressure is the force applied per unit area and its unit is newton per meter square or dyne per centimetre square.

So,

$Pressure = \frac{force}{area} = \frac{100}{2} = 50 \: dyne \: {cm}^{ - 2}$

Pressure in Pascal is equal to newton per meter square.

1 Pascal = 10 dynes per centimetre square.

So,

$50 \: dyne \: {cm}^{ - 2}$

$50 \times \frac{1 ({newton \: {m}^{} }^{-2} )}{10(dyne \: {cm}^{ - 2})} \: dyne \: {cm}^{ - 2} = 5 \: newton \: {m}^{-2} = 5 \: pascal$

Henceforth, the pressure produced in Pascal is 5 Pascal.
