Two pendulums suspended from the same point have lengths of \(2\) m and \(0.5\) m. If they are displaced slightly and released, then they will be in the same phase when the small pendulum has completed:
1. \(2\) oscillations
2. \(4\) oscillations
3. \(3\) oscillations
4. \(5\) oscillations
If the time of mean position from amplitude (extreme) position is 6 seconds, then the frequency of SHM will be:
1. | \(0.01\) Hz | 2. | \(0.02\) Hz |
3. | \(0.03\) Hz | 4. | \(0.04\) Hz |
Which one of the following statements is true for the speed 'v' and the acceleration 'a' of a particle executing simple harmonic motion?
1. | The value of a is zero whatever may be the value of 'v'. |
2. | When 'v' is zero, a is zero. |
3. | When 'v' is maximum, a is zero. |
4. | When 'v' is maximum, a is maximum. |
