Identify the correct definition:
1. | If after every certain interval of time, a particle repeats its motion, then the motion is called periodic motion. |
2. | To and fro motion of a particle is called oscillatory motion. |
3. | Oscillatory motion described in terms of single sine and cosine functions is called simple harmonic motion. |
4. | All of the above |
(A) | parabolic path |
(B) | elliptical path |
(C) | periodic motion |
(D) | simple harmonic motion |
1. | (B), (C), and (D) only |
2. | (A), (B), and (C) only |
3. | (A), (C), and (D) only |
4. | (C) and (D) only |
1. | \( \frac{T}{12} \) | 2. | \(\frac{5 T}{12} \) |
3. | \( \frac{7 T}{12} \) | 4. | \(\frac{2 T}{3}\) |
1. \(25~\text{Hz}\)
2. \(50~\text{Hz}\)
3. \(12.25~\text{Hz}\)

1. | the motion is oscillatory but not SHM. |
2. | the motion is SHM with an amplitude \(a\sqrt{2}\). |
3. | the motion is SHM with an amplitude \(\sqrt{2}\). |
4. | the motion is SHM with an amplitude \(a\). |
One end of a spring of force constant \(k\) is fixed to a vertical wall and the other to a block of mass \(m\) resting on a smooth horizontal surface. There is another wall at a distance \(x_0\) from the block. The spring is then compressed by \(2x_0\)
1. | \(\frac{1}{6} \pi \sqrt{ \frac{k}{m}}\) | 2. | \( \sqrt{\frac{k}{m}}\) |
