The breaking strength of a cable of diameter 2 cm is `2 xx 10^(5)` N. What will be the breaking strength of a wire of the same material but having diameter 1 cm ?

A

`2 xx 10^(5)` N

B

`1xx10^(5)N`

C

`0.5xx10^(5)N`

D

`0.25xx10^(5)N`

Text Solution

Verified by Experts

The correct Answer is:
C
Since area of cross-section has decreased by a factor of 4, the breaking strength becomes `1/4th` of its original value.
Correct choice is (c).
