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
1. | \(0.01~\text{Hz}\) | 2. | \(0.02~\text{Hz}\) |
3. | \(0.03~\text{Hz}\) | 4. | \(0.04~\text{Hz}\) |
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. |
