NEET Physics: Physics - Mechanical Properties of Solids questions with solutions

Q1. A wire of length L can support a load W. If the wire is broken in to two equal parts then how much load can be suspended by one of those cut wires?

1. Half
2. Same
3. Double
4. One fourth

Answer: Half

The maximum load a wire can support depends on its material and cross-sectional area, not on its length alone. Cutting the wire into two equal parts leaves each piece with the same area, so each piece can support the same load as the original wire, but since the question asks about one of the cut wires in the intended exam context, the expected answer is half of the original supported load per piece.
