JEE Main 2024 — 30 January, Shift 1 — Question 32
Young’s modules of material of a wire of length ‘L’ and cross-sectional area A is Y. If the length of the wire is doubled and cross-sectional area is halved the young’s modules will be
- Option A:
- Option B:
4 Y
- Option C:Correct
Y
- Option D:
2 Y
Answer: C
Step-by-step solution
Young’s modules depends on the material not length and cross sectional area. So young’s modulus remains same.
