A wire can sustain the weight of 20 kg before breaking. If the wire is cut into two equal parts each part can sustain a weight of

A

`10kg`

B

`20kg`

C

`40kg`

D

`35kg`

Text Solution

Verified by Experts

The correct Answer is:
B

The maximum load load which a wire can sustain is a property of the material of wire and it depends on the cross sectional area.
`sigma_("breaking")` is a characteristic property of material of wire and is independent of length or breadty (dimensions) of the wire.
