Two springs A and B (k_A=2k_B) are stretched by applying forces of equal magnitudes at the force ends. If the energy stored in A is E, that in B is

Two springs A and B (k_(A)=2k_(B)) are stretched by applying forces of equal magnitudes at the four ends. If the energy stored in A is E, that in B is :

Two springs P and Q of force constant k_p and k_q ( k_Q=k_P/2 ) are stretched by applying forces of equal magnitude. IF the energy stored in Q is E, then the energy stored in P is
