$A$ wire of length $100 \ cm$ and area of cross-section $2 \ mm^2$ is stretched by two forces of each $440 \ N$ applied at the ends of the wire in opposite directions along the length of the wire. If the elongation of the wire is $2 \ mm$,the Young's modulus of the material of the wire is:
- A$4.4 \times 10^{11} \ Nm^{-2}$
- B$1.1 \times 10^{11} \ Nm^{-2}$
- C$2.2 \times 10^{11} \ Nm^{-2}$
- D$3.3 \times 10^{11} \ Nm^{-2}$

View SolutionThe length of a wire becomes $l_1$ and $l_2$ when $100\,N$ and $120\,N$ tensions are applied respectively. If $10l_2 = 11l_1$,the natural length of the wire will be $\frac{1}{x} l_1$. Here,the value of $x$ is ........
On increasing the length by $0.5\, mm$ in a steel wire of length $2\, m$ and area of cross-section $2\, mm^2$,the force required is ($Y$ for steel $= 2.2 \times 10^{11}\, N/m^2$).

View Solution$A$ uniformly tapering conical wire is made from a material of Young's modulus $Y$ and has a normal,unextended length $L$. The radii at the upper and lower ends of this conical wire have values $R$ and $3R$,respectively. The upper end of the wire is fixed to a rigid support and a mass $M$ is suspended from its lower end. The equilibrium extended length of this wire would be:
