A stress of `10^(6) Nm^(-2)` is required for breaking a material. If the density of the material is `3 xx 10^(3) kg m^(-3)`., then what should be the length of the wire made of this material, so that it breakes under its own weight?

A

17 m

B

34 m

C

22 m

D

43 m

Text Solution

Verified by Experts

The correct Answer is:
B
Breading stress `=rho l g`
`therefore l=("Breading stress")/(rho g)`
`=(10^(6))/(3xx110^(3)xx10)=(100)/(3)=33.3 m`.
