If a steel wire of diameter 2 mm has a breaking strength of `4xx10^(5)N`. Then the breaking strength of similar wire of diameter 1 mm will be

A

`4xx10^(5)N`

B

`2xx10^(5)N`

C

`1xx10^(5)N`

D

`0.5xx10^(5)N`

Text Solution

Verified by Experts

The correct Answer is:
C

Breaking strength `prop d^(2)` since the diameter reduced to half, the breaking strength reduced one-fourth.
