Question

What will be the force required to exert a pressure of 20000 Pascal in an area of 1cm2

Answer 1

=) pressure( p) =20000 Pa

=). area (A) =1 cm^2 = 1 / 100×100 m^2

so according to the formula..

=) P = F/A

=). F = P × A

=). F = 20000 × 1/ 10000 = 2 N ans

Answer 2

Given,

Amount of pressure=20000pascal

Area=1cm²

To Find,

Force required.

Solution,

Pressure, P =20000 Pa

Area given, A =1 cm²= 1 / 100×100 m²

So we have the formula for pressure,

P = F/A

⇒F = P × A

⇒ F = 20000 × 1/ 10000

        = 2 N

Hence, Force required will be 2N.
