Q95. A tension of 22 N is applied to a copper wire with an initial cross-sectional area of 0.02 cm2. Given that the Young's modulus of copper is 1.1 × 1011 N/m2 and its Poisson's ratio is 0.32, what is the magnitude of the decrease in the cross-sectional area?Physics — NUST Mock By IBAGRADS 5 — Question 95 of 200A. 1.28 × 10-6 cm2B. 1.60 × 10-6 cm2C. 2.56 × 10-6 cm2D. 0.64 × 10-6 cm2Practice more Physics MCQs for entrance exam preparation on Examora.io.← Previous Question Next Question →
