Correct Answer: Option D
Explanation:
Young's modulus \(\frac{stress}{strain}\)
Strain = \(\frac{e}{l} = \frac{0.05}{10} = \frac{10^{7}}{0.005}\)
2 x 10\(^{9}\)Nm\(^{-2}\)
Young's modulus \(\frac{stress}{strain}\)
Strain = \(\frac{e}{l} = \frac{0.05}{10} = \frac{10^{7}}{0.005}\)
2 x 10\(^{9}\)Nm\(^{-2}\)
