A stress of

10^6 \mathrm{Nm}^{-2}

is required for breaking a material. If the density of the material is

3 \times 10^3 \mathrm{kgm}^{-3}

, then what should be the length of the wire made of this material, so that it breaks under its own weight?

View answer and explanation

Correct option: B

33.3 \mathrm{~m}

Option B (

33.3 \mathrm{~m}

) is correct because the length is calculated by equating the stress due to the wire's weight to the breaking stress of the material.
