If the length of a wire is made double and radius is halved of its respective values. Then, the Young's modules of the material of the wire will:
1 Remains same
2 Become 8 times its initial value
3 Become $\left(\frac{1}{4}\right)^{\text {th }}$ of its initial value
4 Become 4 times its initial value
Explanation:
A Young's modulus (Y) is the property of the material. It does not depends upon the length and radius of the material and independent of the dimension of the wire. So young modulus of the wire will remain same.

The stress at which extension of a material takes place more quickly as compare to the increase in load is called
1 Elastic point
2 Plastic point
3 Breaking point
4 None of the above
Explanation:
D If the yield point passes, some fraction of the deformation will be permanent and irreversible.

A wire breaks if stretched by more than $l$. It is now cut into two equal parts. Then each part can be stretched without breaking by
1 $l$
2 $\frac{l}{2}$
3 $2 l$
4 $\frac{l}{4}$
Explanation:
B For the same breaking stress, same strain is needed. So, $\quad \frac{l}{\mathrm{~L}}=\frac{\mathrm{x}}{\mathrm{L} / 2} \Rightarrow \mathrm{x}=l / 2$

The ratio of lateral strain to the longitudinal strain is called
1 Young's modulus of elasticity
2 Bulk modulus of elasticity
3 Poisson's ratio
4 elastic limit
Explanation:
C Poisson's ratio $(\sigma)$ :- The ratio of lateral strain to the longitudinal strain is called as passion ratio. Young's modulus of elasticity :- It is the ratio of stress to the strain within the elastic limit.
