A compound bar consists of two bars of equal length. Steel bar cross-section is 3500 $$mm^{2}$$ and that of brass bar is 3000 $$mm^{2}$$. These are subjected to a compressive load 100,000 N. If $$E_b=0.2$$ $$\frac{MN}{mm^{2}}$$, the stresses developed are

A

$$\sigma_b=10\frac{N}{mm^{2}},\sigma_s=20\frac{N}{mm^{2}}$$

B

$$\sigma_b=8\frac{N}{mm^{2}},\sigma_s=16\frac{N}{mm^{2}}$$

C

$$\sigma_b=6\frac{N}{mm^{2}},\sigma_s=12\frac{N}{mm^{2}}$$

D

$$\sigma_b=5\frac{N}{mm^{2}},\sigma_s=10\frac{N}{mm^{2}}$$
