Young's ModulusHardQuestion 6309

Question

Two wires (same material, same L). Wire B has double the radius. Same force applied. Ratio extension A/B:
  1. A
    4
    Correct
  2. B
    2
  3. C
    1/2
  4. D
    1/4

Correct answer

4

Explanation

ΔL = FL/AY ∝ 1/A ∝ 1/r². r_B = 2r_A. ΔL_A/ΔL_B = r_B²/r_A² = 4. 4.
