Here's the solution to the problem: Step 1: Identify the given values and the formula for stress. The force applied, F = 20\, N. The cross-sectional area, A = 5\, cm^2. The formula for stress () is: = (F)/(A) Step 2: Convert the cross-sectional area from cm^2 to m^2. Since 1\, m = 100\, cm, then 1\, m^2 = (100\, cm)^2 = 10000\, cm^2. Therefore, to convert cm^2 to m^2, we divide by 10000. A = 5\, cm^2 × 1\, m^210000\, cm^2 = 5 × 10^-4\, m^2 Step 3: Calculate the stress using the formula. Substitute the force and the converted area into the stress formula: = 20\, N5 × 10^-4\, m^2 = (20)/(5) × 10^4\, N/m^2 = 4 × 10^4\, Pa The stress is 4 × 10^4\, Pa.
