Two springs of constants k₁ and k₂ have equal maximum velocities, when executing simple harmonic motion. The ratio of their amplitudes (masses are equal) will be: (A) \(\frac{k_1}{k_2}\) (B) \(\frac{k_2}{k_1}\) (C) \(\left(\frac{k_1}{k_2}\right)^{1/2}\) (D) \(\left(\frac{k_2}{k_1}\right)^{1/2}\) Correct Answer (D) \(\left(\frac{k_2}{k_1}\right)^{1/2}\) Solution: The maximum velocity (\(v_{max}\)) in SHM is given by: \[v_{max} = A\omega\] Where \(\omega = \sqrt{\frac{k}{m}}\). Since the masses (\(m\)) and maximum velocities are equal for both springs: ...
