Question

The maximum load a wire can withstand without breaking, when its length is reduced to half of its original length, will (A) be doubled (B) be half (C) be four times (D) remain same

Breaking force = Breaking stress × Area of cross-section. When the wire is cut to half, there is no change in the area of cross-section of the wire. Therefore, there is no change in the maximum load (i.e., breaking force) the wire can support.
