Question

The Young's modulus of a material of wire is 12.6 × 10¹¹ dyne /cm². Its value in MKS system is :

(1) $12.6 \times 10^{12} \mathrm{~N} / \mathrm{m}^{2}$

(2) $12.6 \times 10^{10} \mathrm{~N} / \mathrm{m}^{2}$

(3) $12.6 \times 10^{6} \mathrm{~N} / \mathrm{m}^{2}$

(4) $12.6 \times 10^{8} \mathrm{~N} / \mathrm{m}^{2}$

Answer 1

It's value in MKS system will be 12.6 × 10¹⁰ N/m². So, The correct option of this question is (2).
