NEET Physics Elasticity MCQ Question
Two wires A and B made of different materials of lengths 6.0 cm and 5.4 cm, respectively and area of cross sections 3.0 × 10⁻⁵ m² and 4.5 × 10⁻⁵ m², respectively are stretched by the same magnitude under a given load. The ratio of the Young's modulus of A to that of B is x : 3. The value of x is

Correct Answer
Detailed Explanation
The Young's modulus is inversely proportional to the product of length and area for the same load and extension. Calculating the ratio gives x = 2.1.
