Solution

The correct option is C
Pa

The area on which the pressure is calculated is ${2 c m}^{2}$ ,

${2 c m}^{2}$ = 2 $\times$ $10^{- 4}$ $m^{2}$

The force applied by the stick is 20N.

So, pressure = $\frac{F o r c e}{A r e a}$ .

pressure = $\frac{20}{2 \times 10^{- 4}}$ = $10^{5}$ Pa.

What is the pressure if a 20 N force is applied over an area of 2cm2?

The correct option is C Pa The area on which the pressure is calculated is 2cm2, 2cm2 = 2 × 10−4 m2 The force applied by the stick is 20N. So, pressure = ForceArea. pressure = 202×10−4 = 105 Pa.
