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 `xx` Area of cross-section . When the wires is cut to half, there is no change in the area of the area of cross-section of their wire. Therefore , there is not change in the area of the maximum load (i.e., braking force ) the wire can support.
