A substance breaks down under a stress of `10^(5) Pa`. If the density of the wire is `2 xx 10^(3) kg//m^(3)`, find the minimum length of the wire which will break under its own weight `(g= 10 ms^(-2))`.

Text Solution

Verified by Experts

The correct Answer is:
5
`Mg=PA: A` is sectional area
`Alqg=10^(5)A`
`l=(10^(5))/(2xx10^(3)xx10)=5m`
