The time period of a pendulum clock is :

Options

A. 1s
B. 2s
C. 1 min
D. 12 h

Explanation

To determine the time period of a pendulum clock, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Time Period**:
The time period (T) of a pendulum is defined as the time taken to complete one full oscillation. This means the pendulum moves from its starting point to one extreme, then to the other extreme, and back to the starting point.

2. **Identify the Movement of the Pendulum**:
When the pendulum swings, it first moves from the center (equilibrium position) to one extreme (let's say the left), and then it moves from the left extreme to the right extreme, and finally returns back to the center.

3. **Calculate the Time for Each Half of the Oscillation**:
According to the information provided, it takes 1 second for the pendulum to move from the center to one extreme (left) and another second to move from that extreme to the other extreme (right).

4. **Total Time for One Complete Oscillation**:
Since it takes 1 second to go from the center to one extreme and another second to return to the center from the opposite extreme, the total time taken for one complete oscillation is:
\[ T = 1 \text{ second (to left)} + 1 \text{ second (to right)} = 2 \text{ seconds} \]

5. **Conclusion**:
Therefore, the time period of the pendulum clock is 2 seconds.

### Final Answer:
The time period of a pendulum clock is **2 seconds**.
