Question

pressure exerted by air on any object is 10 ^5 Pascal. 2m^2 surface area experience the force of air :

Answer 1

$\: \: \: \: \: \: \: \: P = \frac{F}{A} \\ = > {10}^{5}Pa= \frac{F}{2 {m}^{2} } \\ = > F = \frac{ {10}^{5} }{2} = 50000 = 5 \times {10}^{4}N.$

Answer 2

Pressure = Force / Area

==> Force = Area × Pressure

Given :

Pressure = 10⁵ Pa

Area = 2 m²

Force = 10⁵ Pa × 2 m²

          = 2 × 10⁵ Pa m²

          = 2 × 10⁵ N

The force applied is 2 × 10⁵ N

Hope it helps ^_^
