Two bodies M and N of equal masses are suspended from two separate massless springs of spring constants k₁ and k₂ respectively. If the two bodies oscillate vertically such that their maximum velocities are equal, the ratio of the amplitude of vibration of M to that of N is:

• A

  $\frac{{\mathrm{k}}_1}{{\mathrm{k}}_2}$

• B

  $\sqrt{\frac{{\mathrm{k}}_1}{{\mathrm{k}}_2}}$

• C

  $\frac{{\mathrm{k}}_2}{{\mathrm{k}}_1}$

• D

  $\sqrt{\frac{{\mathrm{k}}_2}{{\mathrm{k}}_1}}$
