Question

Force of 2n is applied aver an area of 1cmsq find pressure in s.i unit

Answer 1

Formula

Pressure = force / area

Change the units

S.I unit of pressure is 1 Pa

1 Pa = 1 N / 1 m²

Convert cm² to m²

1 cm² = 1 cm × 1 cm

         = 1/100 m  × 1/100 m

         = 10⁻² m × 10⁻² m

         = 10⁻²⁻² m²

         = 10⁻⁴ m²

Finding the pressure

P = F / A

==> P = 2 N / 10⁻⁴ m²

         = 2 × 10⁴ Pa

         = 20,000 Pa

ANSWER :

The pressure is 20,000 Pa

Hope it helps :-)
