58. In steel, the Young’s modulus and the strain at the breaking point are

In steel, the Young’s modulus and the strain at the breaking point are 2×10¹¹ N/m² and 0.15 respectively. The stress at the breaking point for steel is therefore

(a) 1.33×10¹¹ N/m²                               (b)  1.33×10¹² N/m²

(c)  7.5×10^–13 N/m²                              (d) 3×10¹⁰ N/m²

Answer-d

(7)
