A wire can sustain a weight of 100 kg before it breaks. The wire is cut into two equal parts. Without breaking each part can hold weight up to:
A wire can sustain a weight of 100 kg before it breaks. The wire is cut into two equal parts. Without breaking each part can hold weight up to:
Show Hint
Tensile strength is an intensive property; it does not change with the length of the wire.

- 50 kg
- 200 kg
- 100 kg
- 40 kg
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
The breaking load (strength) of a wire depends on its cross-sectional area and the material properties (tensile strength), not its length.
Step 2: Analysis
When a wire is cut into two equal parts, the cross-sectional area and the material of each piece remain the same as the original wire. Since the breaking load is directly proportional to the area, it remains unchanged.
Step 3: Conclusion
Each piece can sustain the same weight as the original wire, which is 100 kg.
Final Answer: (C)
