Experimental Physics Question 4
Question 4 - 2024 (30 Jan Shift 1)
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 then Young’s modules will be :
(1) $\frac{Y}{4}$
(2) $4 Y$
(3) $\mathrm{Y}$
(4) $2 \mathrm{Y}$
Show Answer
Answer: (3)
Solution:
Young’s modulus depends on the material not length and cross sectional area. So young’s modulus remains same.
