Work, Energy and Power · Potential energy and conservation

Two blocks with masses 100g and 200g 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 kAk_A, kBk_B of A and B, respectively satisfy the relation 4kA=3kB4k_A = 3k_B, is:
  1. (1)4E
  2. (2)2E
  3. (3)3E
  4. (4)43\dfrac43E
