Two blocks with masses $\displaystyle 100$ g and $\displaystyle 200$ g are attached to the ends of springs $\displaystyle A$ and $\displaystyle B$ as shown in figure. The energy stored in $\displaystyle A$ is $\displaystyle E$. The energy stored in $\displaystyle B$, when spring constants $\displaystyle k_A, k_B$ of $\displaystyle A$ and $\displaystyle B$, respectively satisfy the relation $\displaystyle 4 k_A=3 k_B$, is :
