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

A

3E

B

$$\frac{4}{3}E$$

C

4E

D

2E
