NEET 2014 Physics Young's Modulus MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Copper of fixed volume V is drawn into wire of length l. When this wire is subjected to a constant force F, the extension produced in the wire is Δl. Which of the following graphs is a straight line?
A
Δl versus 1/l
B
Δl versus l²
C
Δl versus 1/l²
D
Δl versus l
Correct Answer
Option A
Detailed Explanation
The extension Δl is inversely proportional to the length l for a given volume and force, making Δl versus 1/l a straight line.
