NEET Physics Stress & Strain MCQ Question

Type: MCQ-numerical-Hard-Class 11

A cylindrical rod of cross-sectional area 5 cm² is subjected to a tensile force of 4000 N. Calculate the stress experienced by the rod.

A

80 Pa

B

800,000 Pa

C

800 Pa

D

8,000,000 Pa

Correct Answer

Option B

Detailed Explanation

Stress is calculated as force per unit area. Using the formula stress = F/A, where F = 4000 N and A = 5 cm² = 5 × 10⁻⁴ m², gives stress = 4000 / (5 × 10⁻⁴) = 800,000 Pa.
