Two objects $A$ and $B$ of equal mass are suspended from two springs of spring constants $k_A$ and $k_B$. If the objects oscillate vertically in such a manner that their maximum kinetic energies are equal,then the ratio of amplitudes of $A$ and $B$ is

  • A
    $\frac{k_B}{k_A}$
  • B
    $\sqrt{\frac{k_B}{k_A}}$
  • C
    $\frac{k_A}{k_B}$
  • D
    $\sqrt{\frac{k_A}{k_B}}$
