If $${{l_1}}$$ and $${{l_2}}$$ are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w1 and w2 acting on strips parallel to $${{l_2}}$$ and $${{l_1}}$$ is
A. $$\frac{{{{\text{w}}_1}}}{{{{\text{w}}_2}}} = \frac{{{l_2}}}{{{l_1}}}$$
B. $$\frac{{{{\text{w}}_1}}}{{{{\text{w}}_2}}} = {\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^2}$$
C. $$\frac{{{{\text{w}}_1}}}{{{{\text{w}}_2}}} = {\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^3}$$
D. $$\frac{{{{\text{w}}_1}}}{{{{\text{w}}_2}}} = {\left( {\frac{{{l_2}}}{{{l_1}}}} \right)^4}$$
