The maximum load a wire can withstand without breaking, when its length is reduced to half of its original length, will

A

be double

B

be half

C

be four times

D

remain same

Text Solution

Verified by Experts

The correct Answer is:
D
Breaking force = breaking stress x area of cross-section of wire i.e. it is independent of length of wire till area of cross-section of wire is constant.
